SUMMARY:Photonics Initiative Seminar: Hari Padma
DESCRIPTION:Dr. Hari Padma\, Case Western Reserve University\nDecoding light-driven quantum materials\nAbstract: Driving quantum materials with intense optical pulses offers a powerful means to control their behavior\, leading to remarkable emergent phenomena such as photoinduced magnetic\, ferroelectric\, and superconducting phases. However\, such phenomena are usually transient\, limited to the sub-picosecond duration of the optical pulse or decaying shortly thereafter. Advancing the design and control of light-driven quantum materials therefore requires targeted strategies to achieve long-lived\, metastable phases. In this talk\, I will describe how symmetry protection leads to electronic metastability in a prototypical cuprate ladder material\, Sr14Cu24O41. This finding is enabled by femtosecond resonant x-ray spectroscopy\, which provides unprecedented access to correlated electronic phenomena far from equilibrium. Our measurements show that the metastability is driven by a transfer of holes from chain-like charge reservoirs into the ladders. This ultrafast charge redistribution arises from the optical dressing and activation of a hopping pathway that is otherwise forbidden by symmetry. Relaxation back to equilibrium is hence suppressed once the optical pulse ceases. Remarkably\, we find that this trapped nonequilibrium electronic distribution hosts a propagating\, collective charge mode that is absent at equilibrium\, representing a possible precursor to superconducting pairing. Our results demonstrate how dressing quantum materials with electromagnetic fields can provide a rational design strategy for nonequilibrium phases of matter. \n\nPadma\, et al.

SUMMARY:Photonics Initiative Seminar: Ventsislav K. Valev
DESCRIPTION:Speaker: Ventsislav K. Valev \nTitle: Polarization-Resolved Nonlinear Optical Activity in Scattering \nAbstract:  Nonlinear optical activity in scattered light\, first predicted in 1979\, has recently become experimentally accessible. The original theory encompassed both elastic scattering and its inelastic counterpart\, hyper-Raman. In elastic scattering\, depending on the ratio between particle size and wavelength\, light scattering is typically classified into Rayleigh\, Mie\, and Tyndall regimes. Their nonlinear counterparts\, hyper-Rayleigh\, hyper-Mie\, and hyper-Tyndall scattering\, arise when the emitted light occurs at harmonic frequencies of the excitation. In chiral systems\, these processes give rise to optical activity\, manifesting as differences in the scattered intensity for opposite polarizations. Recent experiments have established nonlinear optical activity across multiple scattering regimes and harmonic orders; even and odd order nonlinearities follow distinct selection rules and probe different aspects of nanomaterials. We have further shown that chiral nanoparticles can transfer chirality to achiral molecules\, giving riseto both Raman and hyper-Raman optical activity. \nSo far\, however\, nonlinear optical activity in scattering has primarily been detected through intensity-based measurements. In this talk\, I will present some of our latest results demonstrating that chirality can also be directly encoded in the polarization state of the scattered light. This observation opens another dimension for probing nonlinear chiral light–matter interactions\, in both elastic and inelastic scattering regimes. \nBio: Ventsislav K. Valev is a Professor of Physics – Laser Nanoscience\, and Associate Dean (Research) at the University of Bath\, UK. He is internationally recognized for his work in nanophotonics and nonlinear optics\, and is a Fellow of Optica\, SPIE\, the Institute of Physics\, and the Royal Society of Chemistry. In 2023\, he was awarded the Thomas Young Medal by the Institute of Physics\, and he has developed a substantial\, award-winning outreach program.

SUMMARY:Photonics Initiative Seminar: Philipp Del Hougne
DESCRIPTION:Universal wave-control framework for extremely tunable microwave systems \nWave-domain programmability emerges as technological enabler of next-generation microwave systems for wireless communications\, sensing\, and wave-domain computing. In this talk\, I will\ndescribe our recent progress toward establishing a universal framework for controlling waves in extremely tunable microwave systems. The predominance of reconfiguration mechanisms based on tunable lumped elements leads to a universal abstraction of these systems in terms of a multiport-network representation\, capable of accurately capturing all relevant electromagnetic interactions between the tunable elements. I will explain how we experimentally calibrate such models for diverse systems such as dynamic metasurface antennas and reconfigurable intelligent surfaces. Then\, I will describe how we navigate the design space based on these models to identify fundamental bounds on realizable functionalities\, as well as configurations closely approaching these bounds. I will outline how these results contribute to the development of a prototype-aware electromagnetic information theory for programmable channels. Finally\, I will discuss principles for system\ndesign to maximize the wave-domain flexibility\, including enhanced dwell times\, non-local programmability\, and time modulation

SUMMARY:Photonics Initiative Seminar: Dimitrios Sounas
DESCRIPTION:Wave Engineering with Active Metamaterials: Nonreciprocity\, Bandwidth Enhancement\, and Analog Computing \nModern technological systems are subject to escalating demands for miniaturization\, speed\, adaptability\, and energy efficiency. Conventional design approaches are increasingly approaching\nfundamental performance limits. Overcoming these constraints requires adopting novel material platforms that are not subject to the constraints of conventional materials. To this end\, time-modulated\, tunable\, and nonlinear metamaterials are particularly promising\, as they enable fundamentally new wave phenomena. In this talk\, I will present our recent theoretical and experimental advances toward the development of electromagnetic devices with unprecedented capabilities for communication and computing systems based on active metamaterials. I will discuss the fundamental physics of time modulated media and demonstrate how they can be engineered to overcome symmetry constraints and bandwidth limitations inherent to passive\ndevices. I will then highlight our progress in linear analog computing with metamaterials\, with particular emphasis on the design of programmable platforms. Finally\, I will present recent results on dynamic effects in nonlinear metamaterials and discuss how these phenomena may enable a new generation of wave-based computing architectures. \nBio: Dimitrios Sounas is an Associate Professor in the Department of Electrical and Computer Engineering at Wayne State University. He focuses on the theory and design of active metamaterials\, with major contributions in the development of nonreciprocal devices. He has authored or co-authored over 100 papers in peer-reviewed journals\, more than 180 conference abstracts\, 6 patents\, and he has received more than 15\,000 citations. \nDimitrios is a Senior Member of IEEE. He is the recipient of the 2020 EurAAP Leopold B. Felsen Award from the European Antennas and Propagation Society and the 2021 Brillouin Medal from the International Phononics Society. He has chaired and organized various sessions in international symposia. He is an Associate Editor for the IEEE Antennas and Propagation Magazine\, a guest editor for Optical Materials Express\, and a reviewer for more than 20 engineering and physics journals.

SUMMARY:Photonics Initiative Seminar: Giovanni Scuri
DESCRIPTION:Heterogeneously integrated photonic systems for quantum science \nPhotonic integration of solid-state quantum emitters offers a promising route to scalable on-chip quantum technologies. Achieving this goal requires combining material platforms that provide both strong opto-electronic tunability and robust qubit coherence. In this talk\, I will discuss our recent progress in characterizing and enhancing the coherence of emerging solid-state spin-qubit systems\, as well as in identifying materials with large electro-optic and piezoelectric nonlinearities at cryogenic temperatures\, where many quantum platforms operate. These results provide a pathway toward realizing heterogeneously integrated quantum devices for applications in quantum simulation and sensing. \nGiovanni Scuri is a postdoctoral researcher in the Department of Electrical Engineering at Stanford University\, working in the group of Professor Jelena Vučković. His work bridges nonlinear optics and solidstate quantum systems\, aiming to build hybrid platforms that enable new capabilities in quantum sensing\, networking\, and simulation. He develops efficient spin-photon interfaces and coherent control techniques for solid-state qubits\, while also exploring novel materials with large electro-optic tunability for next-generation active photonic and quantum interconnect technologies. For this research\, he was awarded the Bloch Postdoctoral Fellowship in Quantum Science and Engineering from the Stanford-SLAC Quantum Initiative (QFARM). Giovanni received a B.A. in Physics from Columbia University and a PhD in Physics from Harvard University. As a doctoral student in Professor Hongkun Park’s group\, he studied excitonic physics in atomically thin semiconductors\, advancing both the understanding of strongly correlated electronic systems and the development of optoelectronic devices at the atomically thin limit.

SUMMARY:Photonics Initiative Seminar: Rainer Hillenbrand
DESCRIPTION:Dr. Rainer Hillenbrand\, CIC nanoGUNE\nPolaritonic Insights from Near-field Nanoscopy:\nFlat-Band Ultrastrong Coupling and Plasmons in Gold Monolayers\n\nAbstract – Scattering-type scanning near-field optical microscopy (s-SNOM) and nanoscale Fourier-transform infrared (nano-FTIR) spectroscopy probe light–matter interactions at the nanoscale using the sharp tip an atomic force microscope (AFM) as an optical antenna. The illuminated tip generates a strongly confined near field that couples to local excitations in the sample\, and the scattered light is recorded to reveal these interactions. These techniques enable the local excitation and detection of\, for example\, phonons\, plasmons\, and polaritons in both bulk and low-dimensional materials across a broad spectral range [1]. After a brief introduction to the technique\, I will present recent studies on polariton mapping. \nUsing pump–probe nano-FTIR\, we investigate the coupling between optical phonons in a thin SiC layer and surface plasmon polaritons (SPPs) in an InAs substrate. By tuning the SPP dispersion to align with the SiC phonon\, we observe ultrastrong coupling with a mode splitting exceeding 20%. Owing to the flat SPP dispersion\, this ultrastrong coupling extends over an unusual wide momentum range\, realizing a flat-band ultrastrong coupling regime [2]. \nWe further apply near-field nanoscopy to study a stable\, quasi-freestanding gold monolayer (ML-Au) formed by intercalating gold atoms between graphene and a SiC substrate [3]. Via polariton interferometry\, we obtain clear evidence of plasmon polaritons. From the experimental images\, we extract the plasmon dispersion and model it with a two-dimensional Drude conductivity. The Drude weight is found to be roughly twice that of bulk gold\, consistent with values obtained from DFT band-structure calculations\, highlighting ML-Au as a promising platform for low-dimensional plasmonics and optoelectronic applications [4]. \n\nHillenbrand et al.\, Nat.

SUMMARY:Photonics Initiative Seminar: Igor Aharonovich
DESCRIPTION:Dr. Igor Aharonovich\, University of Technology Sydney\nQuantum Technologies with Hexagonal Boron Nitride\nAbstract – Engineering robust\, solid‐state quantum systems is amongst the most pressing challenges to realise scalable quantum photonic circuitry. In recent years\, quantum emitters in hexagonal boron nitride (hBN) have emerged as fascinating candidates for realisation of room temperature quantum technologies with hBN. \nIn this presentation I will discuss the photophysical properties of quantum emitters in hBN and expand on their utility in scalable quantum technologies. I will focus on avenues to engineer these defects and describe their most promising properties – including their spin – photon interfaces. Integration of the emitters with photonic resonators is in the heart of achieving quantum circuitry on chip\, and I will present our most recent attempts to achieve this goal. Taking advantage of the unique 2D nature of hBN\, I will also show potential assembly of quantum optoelectronic devices and discuss potential on chip tunability of quantum emitters in hBN. \nAll in all\, hBN possesses all the vital constituents to become the leading platform for integrated quantum photonics. To this extent\, I will highlight the challenges and opportunities in engineering hBN quantum photonic devices and will frame it more broadly in the growing interest with 2D materials nanophotonics. \n \nBio – Igor Aharonovich is an award-winning scientist working on cutting-edge research into quantum sources that are able to generate\, encode and distribute quantum information. A Professor in the School of Mathematical and Physical Sciences at UTS\, Igor investigates optically active defects in solids\, with the aim of identifying a new generation of ultra-bright solid state quantum emitters. He is a chief investigator at the ARC Centre of Excellence for Transformative Meta-Optical Materials (TMOS)\, and leads an international collaboration investigating the chemical structure of crystal imperfections\, or defects\, in the nanomaterial hexagonal boron nitride (hBN). In 2013\, he established the nanophotonics research group at UTS\, was promoted to Associate Professor in 2015\, and to a full Professor in 2018. His research group explores new quantum emitters in wide bandgap materials\, with the aim of fabricating quantum nanophotonic devices on a single chip for the next generation of quantum computing\, cryptography and bio-sensing. In 2016\, Igor and his team discovered the first quantum emitters in 2D materials that operate at room temperature based on defects in hBN. He has co-authored more than 200 peer-reviewed publications\, including one of the most cited reviews on diamond photonics. He has also written a road map for solid state single-photon sources. In 2019\, Igor co-founded the inaugural online photonics conference\, Photonics Online Meetup\, which attracted more than 1100 attendees from around the world\, and which was highlighted by top science outlets. The conference now runs twice a year. Igor has received several international awards including the Pawsey Medal (2017)\, the IEEE Photonics Young Investigator Award (2016) and in 2020 he was the recipient of the Kavli Foundation Early Career Lectureship in Materials Science from Materials Research Society.

SUMMARY:Photonics Initiative Seminar: Matthew White
DESCRIPTION:Dr. Matthew White\, University of Vermont\nHost: Matthew Sfeir \nMetal-dielectric photonic crystal organic light emitting diodes: band structure\, defect engineering\, and topological states.\nAbstract: We investigate the band structure of metal-dielectric photonic crystals comprising stacked organic semiconductor microcavities with silver metal mirrors. Employing organic semiconductor dielectric layers allows the unit cells in the crystal to function as optoelectronic devices including OLEDs and photodetectors\, whether addressed individually or collectively. Geometric variables and material composition are presented to tune the band structure and corresponding photonic wave functions within the crystal. When single defects are introduced into crystals\, individual unit cells with aperiodic dimensionality of the organic dielectric layer\, the resulting mid-gap defect states are shown to hybridize with a photonic band at certain resonant dimensions. The resonance of the defect cavity affects the transmittance of light through the device\, disrupting or enhancing the coupling between otherwise resonant cavities. If the defect is periodic throughout the crystal\, the effects on band structure are very different.  We introduce a periodic defect to every other metal layer\, which doubles the size of the unit cell and has previously been shown to induce a Peierls bandgap.  Defining a ratio R of the thickness of the even numbered and odd numbered metal layers\, the condition R=1 results in no Peierls gap as the cavities are uniform. We demonstrate that by varying that ratio from R<1 to R>1\, there is a point where the band collapses resulting in topological edge states\, heavily localized in the two outer-most cavities.  Topological domain walls are introduced within the bulk of a crystal with similar properties to soliton-like domain walls in the Su-Schrieffer-Heeger model. \nBiography: Matthew White is an Associate Professor of Physics and the director of the Materials Science Graduate Program at the University of Vermont.  His research focuses on materials and devices for light harvesting and light emission\, ranging from stability of commercial photovoltaic modules to nanostructured photonic devices.  Prior to joining UVM\, he was a postdoctoral researcher and then a fixed-term assistant professor in the Institute for Physical Chemistry at the Johannes Kepler University in Linz\, Austria.  He earned his PhD in Physics from the University of Colorado\, Boulder\, and a BS in Physics and Mathematics from the University of Washington. \nZoom Meeting ID 840 7627 0380 Passcode 908949 \n2025 12 02 Photonics Seminar flier Matthew White

SUMMARY:Photonics Initiative Seminar: Siddhartha Ghosh
DESCRIPTION:Dr. Siddhartha Ghosh\, Northeastern University\nAcoustic wave microsystems for chip-scale RF and optical signal processing\nAbstract:  Acoustic waves are well-suited for a variety of signal processing applications including RF filtering and optical modulation. Advances in material and fabrication capabilities have enabled the demonstration of chip-scale subsystems in which phonons can exhibit strong interactions with a variety of other physical domains. This talk will discuss progress in the areas of acousto-electric (AE) amplification and acousto-optic (AO) modulation as well as present the development of a phononic integrated circuit platform. \nIn recent years\, non-reciprocal and switchable delay lines have generated great interest for applications in full duplex radio networks. As a result\, AE-based approaches to mitigating signal interference in the RF front end have been sought. Here we will consider the use of bonding processes for integrating thin film silicon and InGaAs on lithium niobate to produce strong non-reciprocity. These results are developed with regard to implementation in analog correlators and non-magnetic circulators. \nNext\, we will discuss the development of piezoelectrically-actuated AO modulators in polycrystalline and doped aluminum nitride (AlN) materials. Optical coupling to AlN thin films is demonstrated in the telecommunications bands\, enabling monolithic integration of photonic and bulk acoustic resonators. Overlap of these fields enables efficient conversion from RF to optical frequencies\, with applications in integrated microwave photonics and quantum information transfer. \nFinally\, we will present the development of phononic integrated circuits (PnICs) in scandium-doped aluminum nitride thin films on sapphire substrates. Here we demonstrate wavelength-scale confinement of guided surface acoustic waves to generate a library of components including bent waveguides\, splitters and directional couplers. The integration of PnICs with AE and AO effects will thus pave the way for a new class of robust hybrid acoustic microsystems for communications and information processing. \nBio: Siddhartha Ghosh is an Assistant Professor in the Department of Electrical and Computer Engineering at Northeastern University. He received the B.S. degree in from Cornell University in 2007\, the M.S.E. degree from the University of Pennsylvania in 2011 and the Ph.D. degree from Carnegie Mellon University in 2015\, all in electrical engineering. From 2015-2020 he was a member of the Technical Staff at MIT Lincoln Laboratory. He has served in the Technical Program Committees for the IEEE MEMS Conference\, the International Frequency Control Symposium (IFCS) and the CLEO Subcommittee on Micro- and Nano-Photonic Devices. He received the DARPA Young Faculty Award in 2023 and the NSF CAREER Award in 2024. His research interests include piezoelectric MEMS\, optomechanical resonators\, oscillator-based computing and acousto-electronic devices. \nZoom Meeting ID 821 2474 3755 Passcode 727052 \n2025 11 24 Photonics Seminar flier Siddhartha Ghosh

SUMMARY:Nanoscience Initiative + Photonics Initiative Seminar:  Dr. Shomeek Mukhopadhyay
DESCRIPTION:Abstract: \nMaterials Synthesis Using Low Temperature Plasmas – from energy storage to superconductivity \nPlasmas comprise of a quasi-neutral assembly of gaseous ions and electrons which exist at high temperatures (fusion) or low pressure (sputtering\, fluorescent lamps etc.)\, has been the workhorse for manufacturing semiconductor materials in the last 50 years. This talk will introduce a different\, ‘non -equilibrium’ plasma system which works at ambient pressure where the electrons are decoupled from ions and neutral atoms\, known as low temperature or atmospheric pressure plasma\, which has gained increasing attention in the last decade. Such systems are commercially used in ozone generation\, PFAS remediation and dental applications. In particular\, low temperature plasmas offer a versatile\, economic and scalable method for fabricating materials that are difficult using standard techniques like sputtering\, e- beam evaporation\, MOCVD or ALD. I will focus on two synthesis applications; \n\ncomplex oxides used in batteries\, supercapacitors and other energy storage applications\nsynthesizing nanocomposites with metal in layered materials like graphene and Boron Nitride which gives rise to disordered superconductivity\n\nFinally I will conclude with some thoughts and observations on materials synthesis under extreme ‘non-equilibrium’ conditions which can allow synthesis and stabilization of phases that normally occur at pressures in the earth’s core. \nResearch is funded by NSF\, ONR and ARO. \nBio: Shomeek Mukhopadhyay is currently a research scientist in Chemical engineering at Yale University. He received his PhD in Physics from Duke University in 2008. After postdoctoral positions at Levich Institute\, Columbia University and UC Riverside he joined Yale University in 2012 working with Eric Brown in Mechanical Engineering and Materials Science. His main research interests are in nanomaterials synthesis with applications in catalysis\, superconductivity\, energy storage and quantum sensing with Lisa Pfefferle. One of the central themes in the current work is to understand and harness the role of strain in 2D and layered materials. The work on plasma based material synthesis is a collaborative effort with York Plasma Institute\, Britain’s largest center for Plasma Research. In addition to research and teaching\, he also founded three startups focused on Synthesis\, PFAS remediation and Additive Manufacturing respectively and holds 5 patents. His work is funded by DOE\, NSF\, ARO and ONR and collaboration with York funded by the Royal Society.

SUMMARY:Photonics Initiative Seminar: Francesco Valenti
DESCRIPTION:Correlation length of radiation-induced errors in superconducting devices\n\nAbstract – Superconducting quantum electronics are a promising avenue towards fully fledged quantum computation. They are currently limited by their short coherence times\, stemming from their sensitivity to perturbations\, which include… very tiny earthquakes! I will show recent work where we measured six superconducting resonators using nanosecond-resolution electronics. High energy particles impinge on the device chip\, and generate athermal phonons that propagate isotropically. Once this wavefront reaches the resonators\, it induces a phase shift: by resolving the differential time of arrival in the resonators\, we implement an on-chip seismic array. Equipped with this tool\, we uncover a millimetric decay for this type of correlated errors. I will discuss the implications for quantum processors\, and possible research avenues towards mitigation.\n\nBio – Francesco Valenti obtained his BSc in materials engineering from Politecnico di Torino (Italy) in 2015\, his MSc in physics at Université Grenoble Alpes (France) in 2017 (where he was also admitted to and completed the “Magistère de Physique” – excellence track in physics)\, and his Ph.D. at Karlsruhe Institute of Technology (Germany) in 2021\, where he worked in the group of Prof. Ioan Pop. His research interests include the design\, fabrication and characterization of microwave devices for quantum information and radioastronomy\, as well as the diagnostics and abatement of quasiparticle poisoning in superconducting quantum circuits. Since 2022 he works at IBM quantum\, where he focuses on the development\, debugging\, deployment and calibration of large scale quantum processors based on transmon qubits. Keen on drawing and painting since childhood\, he lives in New York City’s East Village\, spending his free time immersed in its rich art scene. \nTarget audience: students and early careers researchers interested in transitioning to industry. \n2025 11 10 Photonics Seminar flier Francesco Valenti

SUMMARY:Photonics Initiative Seminar: Maria Antonietta Loi
DESCRIPTION:Dr. Maria Antonietta Loi\, University of Groningen \nCOLLOIDAL QUANTUM DOT SUPERLATTICES: TOWARDS OPTOELETRONIC METAMATERIALS \nAbstract – 3D superlattices made of colloidal quantum dots are a promising candidate for the next generation of optoelectronic devices as they are expected to exhibit a unique combination of tunable optical properties and coherent electrical transport through minibands. In my presentation I will show the fabrication of 3D superlattices of PbSe and PbS QDs with nanoscale-level controlled ordering over large areas [1\, 2]\, and of outstanding transport properties. The measured electron mobilities for PbSe superlattices are the highest ever reported for a self-assembled solid of fully quantum-confined objects (electron mobility up to 278 cm2 V−1 s−1). This ultimately demonstrates that optoelectronic metamaterials with highly tunable optical properties (in this case in the short-wavelength infrared spectral range) and charge mobilities approaching that of bulk semiconductor can be obtained. This finding paves the way toward a new generation of optoelectronic devices. \nReferences:  \n[1] J. Pinna\, R. Mehrabi Koushki\, D. S. Gavhane\, M. Ahmadi\, S. Mutalik\, M. Zohaib\, L.

SUMMARY:Photonics Initiative Seminar: Junichiro Kono
DESCRIPTION:Dr. Junichiro Kono\, Rice University\nCavity-Dressed Quantum Matter \nAbstract – There has been a growing realization that the properties of a material can be modified just by placing it in an optical cavity. The quantum vacuum fields surrounding the material inside the cavity can cause nonintuitive modifications of electronic states through ultrastrong vacuum–matter coupling\, producing a vacuum-dressed material with novel properties. Existing theoretical predictions include cavity-enhanced\, cavity-induced\, and cavity-mediated enhancement of electron–phonon coupling and superconductivity\, electron pairing\, anomalous Hall effect\, ferroelectric phase transitions\, quantum spin liquids\, and photon condensation. Achieving the so-called ultrastrong coupling (USC) regime is a prerequisite for observing these effects\, which arise when the interaction energy becomes a significant fraction of the bare photonic mode and matter excitation frequencies. Most intriguingly\, when a material is ultrastrongly coupled with cavity-enhanced vacuum electromagnetic fields\, its ground state will contain virtual photons. This nonperturbative virtual driving without external fields can lead to phase transitions in thermal equilibrium. This talk will describe our recent studies of USC phenomena in various solid-state cavity quantum electrodynamics systems in search of such vacuum-induced phases of matter. We utilize the phenomenon of Dicke cooperativity\, i.e.\, many-body enhancement of light–matter interaction\, to explore quantum-optical strategies for creating\, controlling\, and utilizing novel phases in condensed matter enabled by the quantum vacuum. \nBio – Junichiro Kono received his B.S. and M.S. degrees in applied physics from the University of Tokyo in 1990 and 1992\, respectively\, and completed his Ph.D. in physics from the State University of New York at Buffalo in 1995. He was a postdoctoral research associate at the University of California Santa Barbara from 1995-1997\, and the W. W. Hansen Experimental Physics Laboratory Fellow in the Department of Physics at Stanford University from 1997-2000. He joined the Department of Electrical and Computer Engineering of Rice University in 2000 as an Assistant Professor and was promoted to Associate Professor in 2005 and to Professor in 2009. He is currently a Professor in the Departments of Electrical & Computer Engineering\, Physics & Astronomy\, and Materials Science & Nanoengineering at Rice University. \n\nProfessor Kono has also founded and implemented multiple education programs\, including the nationally recognized international research experience program called NanoJapan. NanoJapan was funded by the U.S. National Science Foundation and received the Heiskell Award for Innovation from the Institute of International Education in 2008. In 2016\, his team was selected by the U.S.-Japan Council to implement TOMODACHI STEM @ Rice\, which serve as a catalyst for female Japanese students interested in science and engineering research and engagement with the U.S. through international research collaborations. Professor Kono is a leader in optical studies of condensed matter systems and photonic applications of nanosystems\, including semiconductor nanostructures and carbon-based nanomaterials. He has made a number of pioneering contributions to the diverse fields of semiconductor optics\, terahertz spectroscopy and devices\, ultrafast and quantum optics\, and condensed matter physics. \nSpecifically\, his high-impact achievements include: exploration of extreme nonlinear optics in semiconductors using small-energy photons; ultrafast optical manipulation of collective spins in ferromagnetic semiconductors; observation of the Aharonov-Bohm effect in carbon nanotubes via magneto-optics; ultrafast and nonlinear optical studies of carbon nanotubes; first observation of superfluorescence in a solid through cooperative recombination of quantum degenerate electron-hole pairs; and demonstrations of the ultrastrong coupling regime in high-Q terahertz cavities. Kono’s research group uses state-of-the-art spectroscopic techniques to probe charge\, spin\, and vibrational dynamics. Their experimental facilities include the RAMBO system — a unique mini-coil-based 30-T pulsed magnet system equipped with ultrafast and nonlinear optical spectroscopy setups.

SUMMARY:Photonics Initiative Seminar:  Giulio Cerullo
DESCRIPTION:Dr. Giulio Cerullo\, Polytechnic University of Milan\n2D semiconductors: a platform for ultrafast photonics\nAbstract – Layered materials consist of crystalline sheets with strong in-plane covalent bonds and weak van der Waals out-of-plane interactions. These materials can be easily exfoliated to a single layer\, obtaining 2D materials with radically novel physico-chemical characteristics compared to their bulk counterparts. 2D semiconductors exhibit very strong light-matter interaction and exceptionally intense and ultrafast nonlinear optical response\, enabling a variety of applications in optoelectronics and photonics. Furthermore\, stacking 2D materials into heterostructures (HS) offers unlimited possibilities to design new materials tailored for applications \nThis talk will review our recent studies on the ultrafast non-equilibrium optical response of transition metal dichalcogenides (TMDs) and their HS. Using high time resolution ultrafast transient absorption (TA) spectroscopy\, we monitor the ultrafast onset of exciton formation in TMDs and the dynamics of strongly coupled phonons. Using helicity resolved TA spectroscopy we time-resolve and control intravalley spin-flip processes. In HS of TMDs we time-resolve ultrafast interlayer hole transfer and interlayer exciton formation processes. We also show that strong exciton nonlinear interactions can lead to a complete quenching of the Rabi splitting in TMD-based microcavities. \nBio – Dr. Giulio Cerullo is a Full Professor with the Physics Department\, Politecnico di Milano\, where he leads the Ultrafast Optical Spectroscopy laboratory\, and currently a Miller Visiting Professor at UC Berkeley. Prof. Cerullo’s research activity concerns on the one hand pushing our capabilities to generate and manipulate ultrashort light pulses\, and on the other hand using such pulses to capture the dynamics of ultrafast events in molecular and solid-state systems. He has published over 550 papers which have received >33000 citations (H-index: 92 on Scopus). He is a Fellow of the Optical Society of America\, of the European Physical Society and of the Accademia dei Lincei and past Chair of the Quantum Electronics and Optics Division of the European Physical Society. He has been General Chair of the conferences CLEO/Europe 2017\, Ultrafast Phenomena 2018 and the International Conference on Raman Spectroscopy 2024. In 2023\, he received the Quantum Electronics Prize of the European Physical Society. He is the co-founder of two spin off companies (NIREOS and Cambridge Raman Imaging). \nThis is an in-person seminar. If you opt to join via zoom use Meeting ID 863 4078 0240\, Passcode 924382

SUMMARY:Photonics Initiative Seminar:  Yohannes Abate
DESCRIPTION:Dr. Yohannes Abate\, The University of Georgia \nThere’s Plenty of Interaction at the Bottom\nAbstract – The formulation of quantum mechanics in the late 1920s forever changed physics. More recently\, quantum materials have emerged\, presenting fascinating opportunities in condensed matter physics. Elementary interactions among elements such as photons\, electrons\, phonons\, and other quasiparticles in quantum materials give rise to the emergence of intriguing phases and offer enormous opportunities for the development of quantum technologies. However\, investigating these interactions at the relevant length scale requires high-resolution methods beyond traditional far-field optical imaging and spectroscopy techniques\, which are constrained by the diffraction limit of light. Interestingly\, during the same period in the late 1920s\, a visionary scientist named Synge introduced a groundbreaking concept that could circumvent the diffraction limit. Synge shared his idea with Einstein\, who encouraged him to publish it. After years of pioneering work by various groups\, a powerful modern nano-optical technique\, a variant of Synge’s original idea has emerged that enables high-resolution exploration of plenty of nanoscale interactions\, some of which I will highlight in this talk. I will present examples from two classes of quantum materials\, correlated oxides and van der Waals (vdW) crystals\, that we studied across the visible to terahertz spectrum. Correlated oxides offer exciting opportunities to reconfigure nano-optoelectronic phenomena\, owing to their highly tunable local optical and electronic properties. Our recent results reveal how external perturbations\, such as applied strain\, fields\, or thermal input\, alter dopant distribution at the nanoscale in correlated oxides\, leading to ordered\, reconfigurable phases. This reconfigurability enables the design of robust artificial synapses and opens new frontiers for fundamental understanding of memory\, learning\, and information retention for brain-inspired information processing. In-plane vdW heterostructures composed of atomically thin monolayers with lateral interfaces\, distinct from vertical heterostructures\, can lead to intriguing physical phenomena arising from various interactions\, including intralayer coupling\, lateral strain\, interface defects\, spin-orbit interaction\, correlated electronic fluctuations\, and 2D alloys at interfaces. I will present recent results that provide quantitative insights into the role of these interactions in altering the complex dielectric function of 2D materials at the nanoscale. \nBio – Dr. Yohannes Abate is the Susan Dasher and Charles Dasher MD Professor of Physics at the University of Georgia and Founding Director of the Quantum Science & Engineering Program (https://quantum.uga.edu/). Abate’s condensed matter physics research interests include investigation of nanoscale and quantum phenomena and interactions in two-dimensional materials\, oxide materials\, and quantum emitters. Particularly his group is fascinated by how non-equilibrium or collective quantum phenomena that occur at the atomic/molecular scale result in nanoscale emergent behavior in quantum materials. His group implements various terahertz\, infrared\, optical spectroscopy and scanning probe techniques with diffraction unlimited spatial resolution. \nProfessor Abate joined the University of Georgia (UGA) as an associate professor of physics in August 2017. He received his PhD in Physics at the University of Iowa in 2006. From 2006-2009 he was a postdoctoral research fellow at the University of California\, Berkeley and Lawrence Berkeley National Laboratory. In September of 2009 he has spent time as a Visiting Scientist at the Nano-Photonics Laboratory\, Max-Planck-Institut für Biochemie\, Martinsried\, Germany. He has received the NSF Career Award (2016) and in 2023 he has been selected by the Gordon and Betty Moore Foundation as one of its 2023 Experimental Physics Investigators. He received the BS degree in physics from Addis Ababa University\, Ethiopia. He is a member of the American Physical Society and Materials Research Society. \n2025 08 28 Yohannes Abate Photonics Seminar flier \nZoom Meeting ID: 873 8977 0653   Passcode: 133893

SUMMARY:Photonics Initiative Seminar: Mohammed Hassan
DESCRIPTION:Dr. Mohammed Th. Hassan\, University of Arizona\nFrom Attosecond Electron Microscopy Imaging To Petahertz Quantum Photonics\nAbstract – We present groundbreaking advancements in ultrafast electron microscopy\, quantum current tunneling in graphene\, and ultrafast squeezed light\, establishing transformative capabilities in attosecond science and technology1\,2. First\, we achieved attosecond temporal resolution in a transmission electron microscope by generating a single isolated attosecond electron pulse\, far surpassing the highest reported imaging resolutions3-5. This novel tool\, termed the “attomicroscope\,” represents the world’s fastest electron microscope\, enabling the imaging and control of electron motion dynamics in graphene. The attosecond electron imaging method offers real-time and spatial insights into the electron motion of neutral matter\, unlocking long-anticipated applications in quantum physics\, chemistry\, and biology5. \nNext\, we report the generation of light-induced quantum tunneling currents in graphene phototransistors in ambient conditions. This phenomenon allows precise measurement and control of field-driven currents\, demonstrating current switching at an unprecedented 630 attoseconds (~1.6 petahertz)6. By modulating the density of photoexcited charge carriers with variable pump laser powers\, we enhanced the graphene phototransistor conductivity and realized various logic gate operations. These findings pave the way for optical switches\, lightwave electronics\, and optical quantum computing7-9. \nLastly\, we extend the use of squeezed light to ultrafast quantum science\, demonstrating the generation of broadband quantum light pulses spanning 0.33 to 0.73 petahertz using a light field synthesizer and four- wave mixing10. These pulses exhibit amplitude squeezing consistent with theoretical predictions\, enabling real-time studies of quantum light-matter interactions. Furthermore\, we demonstrate binary digital data encoding onto these synthesized attosecond-resolved quantum light waveforms\, showcasing potential applications in secure quantum communication. This work sets the stage for ultrafast quantum optoelectronics\, next- generation quantum computing\, and encrypted communication networks capable of petahertz-scale data transmission speeds. \nReferences\n[1] Corkum\, & Krausz\, F.

He earned his Ph.D. from the Max Planck Institute for Quantum Optics in Munich\, Germany\, in 2013\, working in the research group of Prof. Ferenc Krausz (Nobel Laureate\, 2023). He then joined the California Institute of Technology (Caltech) as a postdoctoral scholar in the group of Prof. Ahmed H. Zewail (Nobel Laureate\, 1999)\, where he conducted research until 2017. \nSome of Dr. Hassan scientific achievements can be summarized as follows: \nDr. Hassan is widely recognized for pioneering the field of attosecond electron microscopy\, introducing the “Attomicroscope“—the world’s fastest electron microscope capable of imaging electron motion in real time. This revolutionary tool has opened a new frontier in ultrafast imaging\, enabling direct visualization of electron behavior in solid-state materials and advancing quantum science. \nDr. Hassan group developed the first petahertz quantum phototransistor \, capable of switching on and off in just 630 attoseconds—a speed equivalent to 1.6 petahertz\, or over a million billion times per second. This unprecedented speed was demonstrated using a novel graphene-silicon-graphene (Gr-Si- Gr) transistor structure\, marking a significant leap toward the future of ultrafast light-driven electronics. \nMost recently\, Dr. Hassan has demonstrated all-optical switching and quantum current switching on the attosecond timescale\, setting a new world record for switching speed. Leveraging his expertise in light field synthesis\, he has also developed methods to digital encode data onto ultrafast laser pulses. Additionally\, he has introduced novel methodologies for sampling ultrafast laser light fields and measuring electronic response delays in neutral matter. \nHis research group has also achieved a major milestone in ultrafast quantum optics by demonstrating amplitude-squeezed quantum light\, which he has applied to developing highly secure\, high-speed quantum communication technologies. \nEarly in his career\, Dr. Hassan developed the light field synthesizer\, which enabled the generation of the first optical attosecond pulse—the shortest light pulse ever recorded\, earning recognition in the Guinness World Records. Using this breakthrough technology\, he measured the time it takes for an electron to respond and move\, providing unprecedented insight into ultrafast electron dynamics. He also utilized synthesized waveforms to generate extreme ultraviolet radiation from solids\, offering a new temporal perspective on high harmonic generation and electron behavior in condensed matter. \nDuring his postdoctoral tenure at Caltech\, Dr. Hassan optimized ultrafast optical gating techniques to generate electron pulses\, achieving the shortest electron pulse in an electron microscope. He also contributed to the first imaging of nanoparticle motion in a liquid state using ultrafast electron microscopy. His early breakthroughs were published in leading scientific journals. \nDr. Hassan’s contributions have earned him numerous prestigious honors\, including the International Max Planck Fellowship (2009)\, the Air Force Young Investigator Award (YIP\, 2019)\, and major research grants from the Gordon and Betty Moore Foundation (2018) and the W. M. Keck Foundation (2019). In 2022\, he received both the Inaugural AFOSR Director’s Research Initiative (DRI) Award and the Historically Black Colleges and Universities and Minority-Serving Institutions (HBCUs/MSIs) Award for his institution.

SUMMARY:Two-part Photonics Initiative Seminar
DESCRIPTION:This is a two-part Photonics Initiative Seminar\, the first part describing information in light structure and the second part about structuring light in the lab. \nDr. Eileen Otte \nBeyond the Beam: The Potential of Light’s Structure\nWhen light interacts with a medium\, its spatial structure – including amplitude\, phase\, polarization\, angular momenta\, and more – is shaped by the medium’s properties across scales\, from the macro to the nanoscale. For example\, sunlight scattered in the blue daylight sky exhibits intriguing polarization patterns that encode the sun’s position—imperceptible to humans but used by insects like bees for navigation. At much the smaller\, molecular level\, the emission pattern of a single fluorescent molecule depends on its dipole orientation\, allowing nanoscale features to be decoded from the structured light it emits. \nInversely\, structured light can also be deliberately engineered\, making it a powerful tool across a wide range of applications\, including optical micro- and nano-manipulation\, motion sensing\, material machining\, and classical as well as quantum communication and encryption. Used in quantum key distribution\, structured light increases the dimension\, enhancing the information capacity per photon\, noise resilience\, and transmission distance. \nWe will explore how encoding and decoding information in the structure of light opens new avenues for advancing cutting-edge applications and emerging technologies. \nBio   Dr. Eileen Otte joined the Institute of Optics at the University of Rochester as a new faculty member in January 2025. Before\, she was a postdoctoral fellow at the Geballe Laboratory for Advanced Materials (GLAM)\, Stanford University\, advised by Prof. Mark Brongersma. Eileen’s research concentrates on the fundamental properties and diverse applications of structured light fields\, in areas such as singular optics\, nanoscale imaging and sensing\, quantum cryptography\, optical manipulation\, and more. In her postdoctoral research\, Eileen focused on nanoscale light-matter interactions\, combining structured light and nanophotonics. \nEileen performed her PhD work at the University of Muenster\, Germany\, and University of the Witwatersrand\, South Africa; it was honored with summa cum laude as well as the WWU Dissertation Award\, and published as a book in the Springer Theses series. She has also received the Research Award 2020 of the Industrial Club Duesseldorf\, was appointed a junior class member of the NRW Academy of Sciences\, Humanities\, and the Arts\, and was listed among the Emerging Leaders 2021 and Emerging Talents 2021 of IOP’s Journal of Optics. Her postdoctoral research was supported by the PRIME fellowship of the German Academic Exchange Service as well as Stanford’s GLAM Postdoctoral Fellowship. \n  \nDr. Michael de Oliveira\nShaping Light on Demand (with a Few Lines of Code)\nImagine sculpting light—twisting\, shaping\, and imprinting it with structure—as effortlessly as editing an image on a screen. In today’s photonics labs\, this is no longer a fantasy. Spatial light modulators (SLMs) have become versatile\, programmable tools that enable real-time control over light’s spatial and temporal properties\, driving advances in areas like microscopy\, optical tweezing\, quantum optics\, and beyond. This talk offers an accessible introduction to the principles and practice of shaping light with SLMs. We’ll unpack how these devices work\, how phase-only modulation can be used to encode both phase and complex amplitude\, and how to generate a wide range of structured beams—from optical vortices and exotic modes to dynamic space-time beams. We’ll walk through intuitive examples\, practical strategies\, and common challenges\, making this tutorial especially valuable for those new to SLMs or curious about integrating them into automated experimental setups. Whether you’re steering beams\, engineering light fields for nonlinear optics\, or encoding information for quantum communication\, this session will provide a clear and engaging foundation for shaping light in the lab. \nBio  Michael de Oliveira spends most of his time convincing light to do increasingly strange and complicated things—twist\, spin\, heal\, or dance through space-time—using devices like spatial light modulators\, metasurfaces and a generous dose of stubborn optimism. His research focuses on shaping light across multiple degrees of freedom—phase\, polarization\, amplitude\, frequency\, and time—to unlock new effects in photonics\, from ultrafast and nonlinear optics to quantum experiments. He firmly believes that light is just misunderstood—and that with enough patience\, whispered incantations to Maxwell\, and elaborate alignment rituals\, it can be made to do almost anything. Probably. \nMichael joined the ASRC and Prof. Andrea Alù’s group in 2025 as a Postdoctoral Research Fellow. He earned his PhD in Physics from the Politecnico di Milano in collaboration with the Italian Institute of Technology\, where he worked under the supervision of Dr. Antonio Ambrosio on multi-degree-of-freedom control of light for advanced photonic applications. Before that\, he completed his BSc in Astronomy & Astrophysics\, BSc (Honors)\, and MSc in Physics with distinction at the University of the Witwatersrand in South Africa\, where he began working with structured light under Prof. Andrew Forbes. \nhttps://gc-cuny-edu.zoom.us/j/83601898127?pwd=JgFROicFhdgwgNush0IbJqyOSfdpP6.1\nMeeting ID: 836 0189 8127       Passcode: 677460 \n2025 07 07 two part seminar

SUMMARY:Photonics Initiative seminar: Wencan Jin
DESCRIPTION:Dr. Wencan Jin\, Auburn University \nHybrid magnon-phonon cavity realized in a magnetoelastic heterostructure\nAbstract – Strong coupling between two quantized excitations leads to a hybridized state that allows to explore new phenomena and technologies. Phononic excitations\, such as long-lived\, high-overtone acoustic waves\, can host many well-isolated modes at the same frequency. Meanwhile\, magnetic excitations or magnons in magnetically-ordered materials show frequency tunability and can strongly couple with phonons. In this study\, using the combination of analytical model\, epitaxial growth\, and spectroscopy characterization\, we design a hybrid magnon-phonon cavity based on the La0.7Sr0.3MnO3/SrTiO3 (LSMO/STO) heterostructure with magnetoelastic coupling at the interface. Ferromagnetic resonance (FMR) measurements demonstrate strong coupling between the Kittel magnon of LSMO and the standing wave of transverse acoustic phonon of STO\, as evidenced by their anticrossings in the FMR spectra. Remarkably\, when the STO undergoes a cubic-to-tetragonal phase transition at TS~105 K\, the Kittel magnon of LSMO splits into three bands due to the anisotropic strains along the [100]\, [010]\, and [001] crystalline orientations\, forming a network of hybrid magnon-phonon modes that are sensitive to strain engineering. Our work highlights high-quality magnetoelastic heterostructures as a suitable material platform to implement magnon-phonon hybrids\, holding the promise of storing\, encoding\, and transducing coherent information between magnon and phonon modes. \nBio – Wencan Jin graduated from Renmin University of China in 2011. He received his Ph.D. from Columbia University in 2017. He then worked as a Postdoctoral Researcher at the University of Michigan\, Ann Arbor and joined Auburn University as an Assistant Professor of Physics and Adjunct Professor of Electrical and Computer Engineering in 2019. His research focuses on optical spectroscopy (Raman\, SHG) and photoemission spectroscopy (ARPES\, XPS) studies of novel quantum materials with emphasis of ferroic orders in 2D vdW materials and complex oxides. \nThis is an in-person seminar.
