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.

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.

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.

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.

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 URL:https://asrc.gc.cuny.edu/event/photonics-initiative-seminar-matthew-white/ LOCATION:ASRC Auditorium\, 85 St. Nicholas Terrace\, New York\, NY\, 10031\, United States CATEGORIES:Photonics END:VEVENT BEGIN:VEVENT DTSTART;TZID=America/New_York:20251205T100000 DTEND;TZID=America/New_York:20251205T110000 DTSTAMP:20251202T153254Z CREATED:20251016T113049Z LAST-MODIFIED:20251202T153254Z UID:10001534-1764928800-1764932400@asrc.gc.cuny.edu 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.

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.

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.

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.

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.

Due to the lack of nanoscale imaging tools that aid the system design\, however\, spatially resolved acoustic metamaterial studies have been mostly demonstrated in systems operating at kilohertz to megahertz frequencies. In this talk\, I will discuss the visualization of gigahertz valley Hall and spin Hall effects in nanoelectromechanical membranes. Propagation of elastic wave through phononic crystals is directly observed by microwave microscopy with unprecedented sensitivity (sub-100fm) and spatial resolution (sub-100nm). The topologically protected edge states are vividly seen in both real space and momentum space. The robust transport is evident from the wave transmission across local disorder and around sharp corners\, as well as the power distribution into multiple edge channels.
