SUMMARY:Photonics Initiative Seminar: Guancong Ma
DESCRIPTION:Non-Abelian Braiding with Sound and Light\nAbstract – Many physics laws and mathematical rules are insensitive to order. For example\, the addition of numbers disregards the sequence order\, e.g.\, 1+2+3=3+1+2. However\, such a commutative property does not always hold. When the outcomes of a set of operations depend on the execution order\, they can become “non-Abelian.” In the 20th century\, non-Abelian mathematical frameworks have played profound roles in formulating many fundamental laws of modern physics. Famous examples include the classification of hadrons and the unification of electro-weak interactions. Classical physics\, such as mechanics\, electromagnetism\, and optics\, were well established before non-Abelian theories came into play. However\, this does not mean non-Abelian effects are absent in the classical world. One prominent example is a Rubik’s Cube—the moves made on the cube do not always commute: two sequential moves done in different orders do not necessarily get the color palettes to the same layout. We then ask: how and when non-Abelian phenomena arise in classical waves? Delving into this question\, our recent works leverage Berry-phase matrices\, which capture the adiabatic evolution of multiple states\, to realize non-Abelian braiding in acoustics [1] and photonics [2]. Here\, the braiding operations are implemented using coupled waveguide arrays\, which are adiabatically modulated along the guiding direction to enforce a multi-state Berry-phase matrix that swaps the modal dwell sites. The evolution of the guiding modes maps to the generators of braid groups. The non-Abelian characteristics are revealed by switching the order of two distinct braiding operations involving at least three modes. Our results offer new perspectives in exploring novel wave-controlling schemes for future technological applications [3]. \n[1] Z.-G. Chen\, R.-Y. Zhang\, C. T. Chan\, and G.

SUMMARY:Photonics Initiative Seminar: Jonathan Pelliciari
DESCRIPTION:Co-sponsored with CCNY. \nUsing Resonant Inelastic X-Ray Scattering to study quantum materials \nAbstract – Modern light sources like the NSLS-II at Brookhaven National Lab deliver bright tunable photons in a wide range of energies from the THz regime up to 100 keV. This allowed the development of scattering techniques relying on the use of atomic resonances enabling the access to the electronic degrees of freedom in materials. Resonant Inelastic X-Ray Scattering (RIXS) is one of these techniques and thanks to the massive development in instrumentation and theory is playing a significant role in the study of quantum materials with contributions in multiple fields such as superconductivity\, quantum magnetism\, 2D materials\, and lately single photon emission. The sensitivity of RIXS to bosonic excitations of different nature (spin\, orbital\, lattice\, and charge) can provide microscopic information on materials as a function of energy and momentum. In my seminar I will start by introducing RIXS its capabilities and limitations\, followed by a description of the experimental components needed to perform high-resolution RIXS and the solution that we developed at BNL. I will then move forward by highlighting three scientific cases in different fields. The first will involve our investigations on superconducting infinite layer nickelates where we studied the evolution of the spin dynamics across the superconducting dome akin to past studies on the cuprates. The second case regards the study of quantum emitters in hBN where in collaboration with CUNY we could unveil vibronic states and connect them to the signals detected in photoluminescence possibly identifying N2 molecular vibrations as the key for the emergence of quantum emission. Finally\, I will conclude by highlighting one of our studies on excitons in 2D van der Waals magnets where we could detect their nature\, evolution as a function of charge transfer energy (and hybridization)\, and their dispersion in momentum space. \n[1] Ament et al.\, Rev.

X 14\, 031007 \nBio – Jonathan (Johnny) Pelliciari is an Associate Scientist at NSLS-II where he uses advanced scattering techniques (including Resonant Elastic and Inelastic X-Ray Scattering RIXS) to investigate the electronic properties of quantum materials. He got a Bachelor and Master degree in Chemistry at the University of Modena and Reggio Emilia (Italy) and a PhD in Experimental Condensed Matter Physics at the Paul Scherrer Institute and University of Fribourg/Freiburg (Switzerland). His research involves the study of electronic orders such charge and spin density waves and the elementary (spin\, charge\, orbital\, and lattice) excitations in superconductors\, low dimensional systems\, and materials displaying metal-to-insulator transitions. Overall\, his research interests span different physical phenomena such as ultrafast phenomena\, unconventional charge density waves\, spin excitations\, superconductivity\, 2D van der Waals systems\, spin liquids\, and quantum emitters. He developed a laser-RIXS setup commissioned at the SIX beamline to study quantum materials and their ultrafast transitions. \nHe has several active collaborations with external universities and research institutes (CUNY\, Stanford\, MIT\, Yale\, Harvard\, University of Zagreb\, and PSI) on different projects.

SUMMARY:Guest Speaker: Job Boekhoven\, PhD
DESCRIPTION:Regulating molecular assembly with chemical fuels—Spinning ribbons\, dissipative structures\, and an approach towards synthetic life \nJob Boekhoven\, PhD\nDepartment of Bioscience\, Technical University of Munich \nAbstract-Molecular self-assembly is the process in which molecules combine into superstructures held together through non-covalent interactions. Over the last decades\, supramolecular chemists have perfected this art\, and we can now create Gigadalton structures in which each atom is placed with angstrom precision. More importantly\, the unique properties of the emerging assemblies have found their way into everyday life\, like\, for example\, the liquid crystals in our displays. Nevertheless\, biology entirely overshadows us regarding assembly with molecular building blocks. Indeed\, the biological cell has the same molecular toolbox for creating structures; it also uses non-covalent interactions to hold molecules together. Biology uses another trick. Biological structures are governed not only by non-covalent interactions but also by reactions forming covalent ones. Arguably\, molecular self-assembly offers the structures; chemical reactions govern the dynamics and functions of these structures. Biological structures are sustained and regulated in the non-equilibrium regime through chemical reaction cycles that convert energy. The implications\, rules\, and mechanisms there are poorly understood. \nIn this lecture\, I will discuss my team’s effort to elucidate the rules of non-equilibrium self-assembly regulated by chemical reaction cycles. Next\, I will describe a simple yet versatile chemical reaction cycle that can be coupled to self-assembly to create chemically fueled assemblies. Finally\, I will highlight three recent examples of chemically fueled\, non-equilibrium assemblies with vastly different properties than their in-equilibrium counterparts—ribbons that spin spontaneously as they consume fuel and dissipative droplets that periodically form and dissolve when fueled continuously. I will close the lecture with our vision towards synthetic life. \nBio-Job Boekhoven is an Associate Professor at the Bioscience Department of the Technical University of Munich in Germany. He received his PhD in Chemistry under Prof. Jan van Esch and Prof. Rienk Eelkema from the TU Delft in 2012. After a postdoc at Northwestern University (2010-2013)\, he started his independent group in 2016 at the Institute for Advanced Study at the Technical University of Munich as a Rudolf Mössbauer Professor. His honors include an ERC Starting grant (2016) and an ERC Consolidator grant (2024). He has received the VCI – Dozentenpreis and is a Max Planck Fellow in the school Matter to Life. \nJob Boekhoven is developing tools to regulate the self-assembly of molecules the way biology does. He is best known for his work on chemically fueled reaction cycles that control the ability of molecules to assemble or phase separate. The resulting materials show exciting new properties\, such as their intrinsic ability to self-heal or their controllable lifetime. Moreover\, the chemically fueled assemblies manifest features we usually associate with living cells\, like the ability to emerge\, decay\, or even self-divide.

SUMMARY:Photonics Initiative Seminar: Yakir Hadad
DESCRIPTION:Exact formulation of the mutual particle-cavity dynamics and its use for the study of loss threshold phenomenon under magnetization\nAbstract – Light-matter interaction plays a pivotal role in pushing forward nanotechnology. A particularly important setup involves a resonating particle\, say an emitting molecule or a macroscopic quasi-statically resonating plasmonic or ferromagnetic sphere\, that is located inside a cavity. \nIn this work\, we provide an analytic formulation for the exact calculation of the mutual dynamics between a resonant particle and a rectangular cavity in which it is located. The particle is assumed to be small on the wavelength\, and thus\, its excitation is dominated by a dipolar response that can be described using the discrete dipole approximation and polarizability theory.  The dipolar response depends on the particle’s polarizability function which encapsulates the particle’s materials and geometry\, and on the local field acting on the particle. In principle\, the latter is nothing more than the backscattering of the particle field by the cavity walls.  However\, its derivation may be challenging since it involves a three-dimensional singularity subtraction of the Green’s function in the cavity and the Green’s function in the free space that are differently represented. In this work\, we discuss the use of a recursive ladder-type process involving alternative Green’s function representations to calculate the local field in a computationally efficient and numerically stable manner. Using this approach\, we solve exactly several strongly coupled particle-cavity systems and calculate the collective resonance frequencies of the system. \nAs a particularly interesting example\, we focus on the case when the plasmonic particle is subject to a static magnetic field\,  . In this case\, its gyrotropic response gives rise to non-reciprocal dynamics of the ambient surroundings.  This dynamics depends on the particle’s excitation\, which in turn depends on the gyrotropic material damping rate  . Thus\, intuitively speaking\, the heavier the gyrotropic material loss is\, the weaker the non-reciprocal response will be. This is indeed the case when the particle is located in free space. However\, when the gyrotropic particle is placed inside a cavity\, we show that the non-reciprocity measure is robust against material loss up to a specific loss threshold\,  that depends on the magnetic biasing . \nBio – Dr. Yakir Hadad received the B.Sc. and M.Sc. degrees (summa cum laude) in electrical and computer engineering from the Ben Gurion University of the Negev\, Be’er Sheva\, Israel\, in 2006 and 2008\, respectively\, and the Ph.D. degree in physical electronics from Tel Aviv University\, Tel Aviv\, Israel\, in 2014.\,From 2015 to 2017\, he was a Post-Doctoral Fellow with the Department of Electrical and Computer Engineering\, The University of Texas at Austin\, Austin\, TX\, USA.

SUMMARY:Guest Speaker: Tanja Weil\, PhD
DESCRIPTION:Synthesis of Interactive Peptide Nanostructures in Living Systems \nTanja Weil\, PhD \nMax Planck Institute for Polymer Research\, Germany \nAbstract- We explore controlled chemical reactions in complex living systems to generate drug molecules\, synthesize peptide nanofibers\, or build new cellular compartments. The introduction of bioresponsive groups enables us to control peptide self-assembly inside the living cell. These groups react in a controlled fashion with cellular stimuli\, including pH\, reactive oxygen species\, glutathione\, and light. The synthetic intracellular peptide nanostructures can interfere with cell respiration\, metabolism\, they can induce controlled cell death\, or activate T-cells. Additionally\, peptide nanostructures can be integrated into the extracellular matrix\, where they facilitate virus binding and enhance the uptake of viral vectors. To optimize the amphiphilic peptide sequences of self-assembling peptides with regard to their multiscale structure formation and bioactivity\, we employ data mining and machine learning tools. \n \nFigure 1. Bioresponsive caged peptide monomers enter living cells and undergo chemical transformations initiated by cellular stimuli and form supramolecular peptide nanofibers that can affect cellular processes. \n\nChagri\, S.; Ng\, D.

SUMMARY:Thesis Defense: Shixiong Yin
DESCRIPTION:Enhanced Light-Matter Interactions in Complex Photonic Systems \nMentor: Andrea Alù \nAbstract  \nInteractions between light and matter are fundamental to breakthroughs in lasers\, sensing\, imaging\, spectroscopy\, energy harvesting\, and quantum information processing. As a result\, significant recent efforts have been geared towards enhancing and controlling light-matter interactions to advance these applications and technologies. Complex engineered photonic systems\, often involving nanoscale designs of photonic components\, have provided fertile grounds to manipulate light unprecedentedly\, achieving extreme control over interactions among photons and between light and matter. In this dissertation\, we exploit four types of complexity to enhance light-matter and light-light interactions in various photonic platforms. \nFirst\, we start by tailoring the spatial complexity in photonic designs\, which can stimulate unusual light interactions with plasmonic materials. In a one-dimensional metamaterial\, i.e.\, an artificially engineered periodic structure\, we show that perturbing the discrete translational symmetry can induce a topological knot in reciprocal space. It enables strong nonlocal coupling between a dark mode and a brighter surface mode\, which offers new opportunities for efficient sensing and Raman scattering. \nIntroducing complexity in the material constituents together with deliberate spatial designs\, we further explore how nonlinearities in metamaterials unleash novel forms of controlling light emission\, leveraging strongly enhanced interactions with light. Besides\, blending different types of materials can also push the limits of complex photonic designs. We design an ultrasmall nanocavity hybridizing two distinct materials — a high-index dielectric encapsulated by the low-loss metal\, demonstrating record-high Purcell enhancement. The proposed hybridized nanocavity is expected to enhance quantum emission and strong coupling substantially. \nAs another degree of freedom\, complexity can be introduced in the temporal dimension. Time variations in material properties provide a new knob for complex photonic designs. Among them\, time-interfaces\, realized by switching the properties of the entire medium in time\, introduce striking complexity in wave dynamics. In a transmission-line metamaterial\, we have observed time reflections at a photonic time interface and associated broadband and ultrafast frequency translation for the first time. Combining multiple time interfaces in the same platform\, we realize a passive photonic time crystal\, which holds the prospect of extreme interaction with light with zero energy cost\, inaccessible in either time-invariant or conventional time-varying systems. \nFinally\, we harness the complexity in the frequency domain. Complex spectral responses and modal patterns can arise in wave-chaotic systems. In this context\, we realize coherent control over photon-photon interactions in a chaotic photonic microcavity involving over a thousand optical modes. Efficient control of its radiation is further demonstrated via reflectionless scattering modes\, paving the way for efficient energy harvesting\, routing\, and conversion. \nZoom Meeting ID: 722 951 7086 Passcode: 2024 \nMembers of the doctoral faculty are invited to attend.

SUMMARY:Thesis Defense: Seungri (Victor) Kim
DESCRIPTION:The Effects of Nanoconfined Liquid Properties on the Water-Responsive Behavior of Bacterial Cell Walls\n  \nAbstract: Water-responsive (WR) materials have the ability to mechanically swell and shrink in response to changes in relative humidity (RH). These WR materials are used by many biological systems to perform essential tasks; for example\, pinecones use WR materials to release their seeds in dry environments\, and wheat awns open and close to propel seeds into the soil\, driven by daily RH changes. The WR actuation of some biomaterials is extremely powerful\, for example Bacillus subtilis cell walls display record-high actuation energy and power densities of 72 MJ m-3 and 9.1 MW m-3\, surpassing those of all existing muscles and actuator materials. They hold great potential to be used as high-performance actuators for various applications\, including energy harvesting\, robotics\, and morphing structures. However\, the fundamental mechanisms of WR actuation are still poorly understood. Despite the unclear WR mechanism\, recent studies have provided compelling evidence of the critical role that the properties of nanoconfined water play in these observed high-power WR actuation\, and thus\, adjusting the properties of nanoconfined water should substantially affect WR behavior and performance. \nThis thesis investigates the role of nanoconfined liquids in the WR actuation of bacterial cell walls\, focusing on how modifying their behavior can improve WR performance. In this research\, cell walls of E. coli\, S. aureus\, S. cerevisiae and B. subtilis were extracted and used to investigate the properties of their nanoconfined water. Based on these findings\, we further explored the effects of kosmotropic and chaotropic solutes\, known to stabilize or disrupt hydrogen bonding networks\, on the WR performance of B. subtilis cell walls. We discovered that cell walls treated with low-concentration kosmotropic solutes exhibited a significant increase in WR actuation energy density\, reaching 103.3 MJ m-3. However\, higher concentrations of kosmotropic or chaotropic solutes led to decreased WR performance. Our observations suggest the presence of an optimal range for kosmotropic and chaotropic treatments to enhance WR energy density. These findings could be explained by the impact of the solutes on hydration forces and intermolecular interactions\, which affect the ultimate WR pressure. This\, in turn\, provides a pathway towards achieving superior WR actuation performance and advancing the development of high-work-density actuator materials for diverse industrial applications. \n  \nPlease use the Zoom meeting link below if you cannot attend in person. \nMeeting ID: https://ccny.zoom.us/j/8366033109?pwd=WTZZVzRNZllQUWhsc2RnRHdiN1hWUT09 \nLink to Announcement \n

SUMMARY:Photonics Initiative Seminar: Bing Cheng
DESCRIPTION:Terahertz probes of quantum matter: from pairing symmetry to high harmonics\nQuantum materials often harbor emergent orders and phases that reveal themselves at low-energy scales\, around 1 to 10 meV. To investigate these collective behaviors\, we turn to the terahertz energy regime—a crucial window for probing and controlling quantum phenomena. In this talk\, I will present our latest breakthroughs in unraveling the superconducting gap structure of the newly discovered unconventional nickelate superconductors— a topic that has sparked intense debate and remains unresolved. Using both linear and nonlinear terahertz spectroscopy\, we uncovered multiple evidence to demonstrate a cuprate-like d-wave gap structure in nickelate superconductors\, providing key insights to steer future research in this field. Expanding beyond understanding\, I will broaden the discussion to the manipulation of quantum materials through light. I will show how we harness intense terahertz pulses to drive the electronic structure of a Dirac semimetal\, leading to the observation of record-breaking terahertz high harmonics. Our findings position topological materials as promising platforms for delving into high harmonic generation and strong-field physics. \nBrief Bio: Bing Cheng earned his Ph.D. in Johns Hopkins University in Sep 2019. Then he moved to Stanford\, and Ames National Lab\, working as a postdoc researcher. At present\, He is working as a research fellow in Prof. Mengkun Liu’s group at Stony Brook University. His research mainly focuses on discovering and understanding exotic quantum phases of matter using a suite of terahertz optics

SUMMARY:Photonics Initiative Seminar: David Burghoff
DESCRIPTION:Nonlinear Photonics in the Mid-Infrared and Terahertz\nAbstract – Optical sensing at long wavelengths presents significant opportunities and significant challenges. The longwave infrared and terahertz ranges are renowned for their potential to sense molecules in a variety of contexts\, such as high-speed chemical imaging\, disease detection\, and environmental monitoring; however\, their promise has yet to be fulfilled due to a lack of compact broadband sources and low-loss integrated photonics platforms. The most important sensing challenges require extremely wideband sources to achieve specificity and selectivity\, but to date\, there are no technologies that are compact\, bright\, and broadband. \nI will discuss some of the work of my group that seeks to address this challenge. First\, I will discuss our development of quantum cascade laser-based frequency combs\, light sources that fill the gap between broadband incoherent sources and lasers. I will also discuss how our experimental investigations of these combs led to my discovery of a new fundamental comb state that manifests in almost any laser at any wavelength\, acting as the phase equivalent of passive modelocking [1]\, [2]. Next\, I will discuss our recent development of ultra-low-loss platforms for long wavelengths based on hybrid photonic integration\, which allowed us to create optical resonators in the longwave infrared with quality factors 100 times better than the state-of-the-art [3]\, [4]. This approach is fully wavelength-scalable and allows for the first efficient nonlinear optics at long wavelengths\, serving as a foundational element for future applications in quantum sensing. Finally\, I will discuss our development of ptychoscopy\, a new sensing modality that allows for ultra-precise measurements of optical spectra. This measurement enables the measurement of remote signals with quantum-limited frequency resolution over the entire bandwidth of a comb\, for the first time allowing incoherent spectra to be characterized with the precision techniques of combs [5]. \n[1] D.

DESCRIPTION:Dr. Mu Wang\nNational Laboratory of Solid State Microstructures\, School of Physics\, and Collaborative Innovation\nCenter of Advanced Microstructures\, Nanjing University\, Nanjing 210093\, China \nManipulating Light with Optical Metasurfaces: from Classical to Quantum\nAbstract – This talk focuses on the interaction of electromagnetic waves with metamaterials and manipulating the polarization state of light\, which are essential for on-chip photonics and quantum information processing. By designing a metasurface based on geometrical-scaling-induced phase modulations\, the transformation and distribution of different polarization-entangled photon pairs have been realized with multichannel dielectric metasurfaces. This is a significant development in applying metasurface to quantum networks. We also show a strategy to overcome the fundamental limit of polarization multiplexing capacity of metasurfaces by introducing the engineered noise to the precise solution of Jones matrix elements\, where the conventional restriction of polarization multiplexing roots from the dimension constraint of the Jones matrix. This approach implies a new paradigm for high-capacity optical display\, information encryption\, and data storage. As a practical application\, we also present a metasurface that achieves a matte appearance in reflection while offering broadband\, perfect transmission\, showcasing its potential for various optical technologies. \nReferences:\nY.J.

Focused ultrasound (FUS) offers an exciting solution by temporarily opening the BBB to allow targeted drug delivery. Yet\, understanding the safety and effectiveness of this approach remains a major challenge. Traditional brain imaging modalities fall short—they either lack the resolution or the sensitivity needed to monitor subtle changes in BBB permeability and the resulting hemodynamic responses. In this talk\, I’ll introduce a groundbreaking multimodality imaging approach: PAUL imaging. By integrating the molecular sensitivity of photoacoustic imaging with the microvascular detail of super-resolution ultrasound localization—and further enhancing it with deep learning—PAUL imaging delivers fast\, high-resolution insights into BBB permeability and cerebral hemodynamics. This powerful platform provides a transformative tool for advancing brain-drug delivery and uncovering the biological impacts of BBB modulation\, opening new avenues in the treatment of neurological disorders. \nBio – Yun-Sheng Chen is an Assistant Professor of Electrical and Computer Engineering at the University of Illinois\, Urbana-Champaign (UIUC)\, where he leads the Multimodality Imaging Research Laboratory.

SUMMARY:Photonics Initiative Seminar: Levent Sevgi (IEEE DL lecture)
DESCRIPTION:Dr. Levent Sevgi\n\nIEEE AP-S Former DL – DLPC Chair\nITU – Istanbul Technical University (Emeritus) \nFrom Engineering Elecromagnetics to Electromagnetic Engineering:Teaching/Training Next Generations\nAbstract – The role of Electromagnetic (EM) fields in our lives has been increasing. Communication\, remote sensing\, integrated command/ control/surveillance systems\, intelligent transportation systems\, medicine\, environment\, education\, marketing\, and defense are only a few areas where EM fields have critical importance. We have witnessed the transformation from Engineering Electromagnetics to Electromagnetic Engineering for the last few decades after being surrounded by EM waves everywhere. Among many others\, EM engineering deals with broad range of problems from antenna design to EM scattering\, indoor–outdoor radiowave propagation to wireless communication\, radar systems to integrated surveillance\, subsurface imaging to novel materials\, EM compatibility to nano-systems\, electroacoustic devices to electro-optical systems\, etc. The range of the devices we use in our daily life has extended from DC up to Terahertz frequencies. We have had both large-scale (kilometers-wide) and small-scale (nanometers) EM systems. A large portion of these systems are broadband and digital and must operate in close proximity that results in severe EM interference problems. Engineers must take EM issues into account from the earliest possible design stages. This necessitates establishing an intelligent balance between strong mathematical background (theory)\, engineering experience (practice)\, and modeling and numerical computations (simulation). \nThis Distinguished/keynote lecture aims at a broad-brush look at current complex EM problems as well as certain teaching / training challenges that confront wave-oriented EM engineering in the 21st century\, in a complex computer and technology-driven world with rapidly shifting societal and technical priorities. \nBio – Prof. Dr. Levent Sevgi is a Fellow of the IEEE (since 2009) and the recipient of IEEE APS Chen-To Tai Distinguished Educator Award (2021).

SUMMARY:Photonics Initiative Seminar: Simo Pajovic
DESCRIPTION:Simo Pajovic\nDepartment of Mechanical Engineering\, Massachusetts Institute of Technology \nControlling Light-Matter Interactions in Novel Emitters:\nThermal Radiation\, Scintillation\, and Beyond\nAbstract – In mechanical engineering\, thermal radiation is the best-known example of light-matter interactions\, but non-thermal radiation is prevalent in a wide variety of applications\, including medical imaging\, manufacturing\, and sensing. Scintillation—the emission of light when a high-energy particle passes through a material—is of particular interest because of its high efficiency\, access to a wide spectral range\, and use in imaging and detection. This process can be modeled using fluctuational electrodynamics similarly to thermal radiation\, meaning they are analogous. In this talk\, I will describe my efforts during my PhD to advance both our fundamental understanding of and critical applications based on control of thermal radiation and scintillation. I will describe how we experimentally observed nonreciprocal reflection of mid-IR light in highly doped InAs at low magnetic fields (< 0.2 T) using both spectroscopic ellipsometry and FTIR. Our work demonstrates that nonreciprocity can be observed at low magnetic fields without coupling to resonant modes\, i.e.\, using a flat surface rather than a patterned surface designed to resonantly interact with light [1]. This advances our fundamental understanding of mid-IR nonreciprocity and has implications for sensing and efficiency of systems such as PV cells. Then\, I will shift gears to X-ray imaging\, where my focus has been on source-to-detector improvements using nanophotonics. First\, I will describe a strategy for increasing the operating power of X-ray tubes using “nanophotonic thermal management.” We theoretically predicted that nanophotonically patterning the anode of an X-ray tube can lead to a 1.25× enhancement in operating power (a proxy for X-ray generation) by enhancing radiative heat transfer between the anode and its surroundings. Second\, I will discuss steps we have taken toward improving the scalability of so-called “nanophotonic scintillators” for X-ray imaging. Using a nanophotonic scintillator with a lateral area of 4 cm × 4 cm\, we imaged a biologically relevant sample for the first time\, paving the way for clinical applications of nanophotonic scintillators [2]. \n[1] S.

SUMMARY:Photonics Initiative Seminar: Giovanni Milione
DESCRIPTION:Dr. Giovanni Milione\n\nNEC Laboratories America\, Inc. \nVector Beams and Space Division Multiplexing\nAbstract – In this talk\, I will overview two areas of my research at NEC Laboratories America\, Inc.: \nFor plane wave solutions to Maxwell’s equations\, light’s polarization is understood. Not so for structured light. In this talk I’ll discuss non-trivial higher-order solutions that have spatially inhomogeneous states of polarization—vector beams. This includes their connection to optical angular momentum\, N-dimensionality\, SU(N)-symmetric Jones/Stokes spaces\, higher-order Poincare sphere and Pancharatnam-Berry phases\, and non-separable space/polarization degrees of freedom. I’ll also discuss their inherentness in circularly symmetric and anisotropic photonic media\, e.g.\, (non)local meta-surfaces\, liquid crystal “q-plates\,” and multimode optical fibers\, and their experimental generation/measurement. \nSpace division multiplexing is the use of spatial modes as multiple\, independent\, and per wavelength data channels. It multiplies data rates (Tb/s- to Pb/s-scales)\, optimizes spectral efficiency\, and increases data capacity of optical communications beyond fundamental limits. In this talk\, I will discuss the ~10-year evolution from research to recent productization via submarine cables\, short reach interconnects\, and satellite links. This comprises the mitigation of mode coupling and dispersion via novel multi-mode/core optical fibers\, the use of optical orbital angular momentum\, vector beams\, and Hermite-Gaussian modes\, the mitigation of atmospheric turbulence-based scintillation via physics-informed use of spatial modes\, and efficient mode multiplexers via photonic lanterns and multi-plane light conversion. \nTime permitting\, I will briefly overview the use of our work applying computational imaging to biometrics\, i.e.\, phase-mask-based privacy preserving cameras for face recognition\, and photoacoustic tomography-based 3D finger vein authentication. \nBio – Dr. Giovanni Milione is a Senior Researcher/Business Incubation Lead in the Optical Networking & Sensing Department at NEC Laboratories America\, Inc. in Princeton\, NJ. He received his B.S. in Physics from Stony Brook University and M.S.\, M.Phil.\, and Ph.D. all in Physics from CUNY Graduate Center/The City College of New York\, where he was a National Science Foundation Graduate Research Fellow. Giovanni’s research includes structured light fundamentals\, space division multiplexing-based optical communications\, and distributed optical fiber sensing\, which has impacted NEC Corporation’s business at a multi-million-dollar global scale. He serves(ed) as technical program committee chair/member for Optica FiO\, CLEO\, IPOEM\, IEEE Photonics Conference\, SPIE Photonics West\, and the International Conference on Optical Angular Momentum.

SUMMARY:Photonics Initiative Seminar: Mikhail Belkin
DESCRIPTION:Dr. Mikhail Belkin\, Technical University of Munich (TUM) \nNew Applications for Nonlinear Intersubband Polaritonic Metasurfaces: from beam shaping to THz generation  \nAbstract – Quantum-engineered intersubband transitions in n-doped multiple-quantum-well heterostructures allow one to produce semiconductor films with very large nonlinear optical response. This nonlinear response can be further enhanced by processing semiconductor heterostructures as metasurfaces in which intersubband transitions are coupled to optical modes of the metasurface nanoresonators [1]. As a result\, one can fabricate optically-thin films of nonlinear optical materials that display second- and third-order nonlinear susceptibility values 4-7 orders of magnitude higher than that of traditional nonlinear optical crystals. Using these films\, one can achieve efficient (0.1-1%) frequency mixing at moderate pumping intensities (10-100 kW/cm) without phase-matching constraints associated with bulk nonlinear optical crystals [2\,3]. In this presentation\, I will discuss our recent advancements with these metasurfaces\, focusing on dynamic electrical phase control of the nonlinear optical response at the individual nanoresonator level [4\,5] and on efficient broadly-tunable continuous-wave terahertz generation via difference-frequency mixing [6]. \n[1] J.

SUMMARY:Guest Speaker: Mathijs Mabesoone\, PhD.
DESCRIPTION:Automation and AI in Molecular Materials Discovery\nAbstract – In my talk\, I will focus on our first results towards establishing a high-throughput synthesis and analysis platform for peptides and peptide derivatives. This platform enables us to perform data-driven active learning for peptide design\, in which we combine experiments with machine learning and AI. We have been using this platform for both fundamental and more applied investigations\, and I will show some results on analysis of fundamental molecular properties\, such as solubility\, and more applied properties\, such as interfacial tension. Lastly\, I will show some of our recent efforts involving infusion of prior literature into our active learning decisions through agentic AI. \nBio – Mathijs received his BSc. and MSc. in chemistry from the Radboud University\, before moving to the Eindhoven University of Technology for a PhD in the group of Bert Meijer. Here\, he worked on model-driven understanding of competitive interactions of solvents and additives in supramolecular polymerizations. In 2021\, Mathijs changed fields and joined the lab of Jörn Piel at the Intsitute of Microbiology at ETH Zurich. During his time at ETH\, Mathijs developed data-driven workflows for natural product discovery and engineering of polyketide synthases. In 2024\, Mathijs joined the Radboud University and Big Chemistry consortium as a group leader. Merging his prior experience in supramolecular chemistry and protein engineering\, his group aims to develop data-driven methods to for peptide material design\, combining high-throughput experimentation with machine learning\, for applications in biomedicine and materials science. \n  \n
