SUMMARY:Photonics Initiative Seminar: Yang Zhao & Yun-Sheng Chen
DESCRIPTION:Dr. Yang Zhao\nUniversity of Illinois\, Urbana-Champaign \nImaging\, Sensing\, and Wearable Devices Using Nanophotonic Platforms\nAbstract – Personalized health emphasizes prevention and early diagnosis over solely tailoring therapies. My lab’s nanophotonic approaches center on developing precision tools to detect biomarkers\, imaging molecular interaction functions\, and designing sustainable wearable devices. In this talk\, I will highlight two research areas: ultrafast optical force nanoscopy and wearable metasurface sensors. I will introduce Decoupled Optical Force Nanoscopy (Dofn)\, a technique that addresses current limits in nanoparticle thermal profiling by enabling nanosecond temporal and nanometer spatial resolutions. Dofn also offers a non-invasive way to identify cell membrane molecules without purification. Next\, I will discuss wearable metasurface-enabled sensors for wireless charging of implanted devices. Tested on live animals\, this technology demonstrates a tenfold power enhancement\, enabling long-term tracking of brain activity. These innovations mark significant strides in wearable sensing for personalized health. \nBio – Yang Zhao is an assistant professor at the University of Illinois\, Urbana-Champaign\, in the Department of Electrical and Computer Engineering. She is affiliated with the Micro and Nanotechnology Laboratory and holds courtesy appointments in Bioengineering\, Institute for Genomic Biology\, and Translational Sciences of Carle Illinois College of Medicine at UIUC. Prof. Zhao received her Ph.D. in Electrical and Computer Engineering from the University of Texas at Austin\, where she was advised by Professor Andrea Alù. Following her Ph.D.\, she served as a postdoctoral research fellow in Materials Science at Stanford University\, under the guidance of Professor Jennifer A. Dionne. Prof. Zhao directs the BioNanophotonics Lab at UIUC. Her research group focuses on studying nanoscale forces and fields by developing optical and nanophotonic tools\, which are instrumental for imaging\, sensing\, and actuation across subwavelength to wavelength scales.

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. Dr. Chen received his Ph.D. from the University of Texas at Austin\, advised by Prof. Stanislav Emelianov\, followed by a postdoctoral fellowship in the Radiology Department at Stanford University’s School of Medicine\, working with Prof. Sam Gambhir. Dr. Chen has been recognized with prestigious honors\, including the Google Faculty Research Award\, the Innovative Science Accelerator Award\, UIUC’s 2024 Dean’s Award for Innovation Impact\, and\, most recently\, the Stephen I. Katz Early-Stage Investigator Research Project Grant from the NIDDK. His research focuses on developing pioneering imaging technologies that integrate light and ultrasound for advanced diagnostics and therapeutics. His work\, published in leading journals such as Nature Nanotechnology\, Nature Biotechnology\, and PNAS\, spans impactful applications in molecular imaging\, neuronal stimulation\, and cancer diagnostics\, contributing to significant advancements in medical imaging and targeted treatment strategies.

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. Pajovic\, Y. Tsurimaki\, X. Qian\, G. Chen\, and S. Boriskina\, arXiv:2410.06596 (2024). In production at Optics Express. \n[2] L. Martin-Monier\, S. Pajovic\, M. Abebe\, J. Chen\, S. Vaidya\, S. Min\, S. Choi\, S. Kooi\, B. Maes\, J. Hu\, M. Soljačić\, and C. Roques-Carmes\, arXiv:2410.07141 (2024). Under review at Nature Communications. \nBio – Simo Pajovic (see-moh pie-oh-vitch) is a MathWorks Engineering Fellow and PhD Candidate co-advised by Dr. Svetlana Boriskina (MechE) and Prof. Marin Soljačić (Physics). Previously\, he was an MIT Presidential Fellow\, an NSF Graduate Research Fellow\, and a DOE SCGSR Fellow (hosted by Los Alamos National Laboratory). As both a theorist and experimentalist\, Simo’s research lies at the nexus of light-matter interactions and critically important applications such as energy and medicine. Research topics he has worked on include electromagnetic nonreciprocity\, thermal radiation\, spatiotemporally modulated metasurfaces\, nanophotonic scintillators\, and free-electron radiation. \nThis is an in-person seminar.

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. Giovanni also served on the Editorial Advisory Committee of Optica’s Optics & Photonics News and was the chair of the Smart Cities Committee of the Fiber Optic Sensing Association. His recent recognitions include Stony Brook University’s 40 Under Forty. Giovanni is also a U.S. military veteran\, having served in the Iraq/Afghanistan wars. \nThis is an in-person seminar.

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

DESCRIPTION:High-resolution in situ Structures within Mitochondria\nMitochondria are essential for ATP production via oxidative phosphorylation\, involving respiratory complexes within the inner membrane. Despite extensive in vitro studies\, understanding their mechanisms in physiological environment is challenging due to loss of the native environment during\npurification. Here\, we directly image porcine mitochondria by developing a high-resolution in-situ cryo-electron microscopy technique\, which enabled us to determine near-atomic structures of various respiratory supercomplexes in the native membrane. \nPlease use this link to access Zoom.

SUMMARY:Photonics Initiative Seminar: Giuseppe Strangi
DESCRIPTION:Dr. Giuseppe Strangi (Case Western Reserve University) \nThin-Film Photonics: Enabling Fano Resonances and Optomechanics\nAbstract – In recent years\, significant interest has emerged in the inverse design1 of artificial layered heterostructures for photonic applications2. Specifically\, the unique optical properties of near-zero permittivity (ENZ) metamaterials have enabled the exploration of novel physical effects and mechanisms. In this presentation\, I will delve into how thin film photonics harnesses the potential of Fano resonances3-4 and extreme optomechanics5. By layering metal-dielectric thin films\, we can create a distinct type of optical coating that exhibits photonic Fano resonance\, referred to as a Fano-resonant optical coating (FROC). We extend the concept of coupled mechanical oscillators to thin-film nanocavities\, shedding light on semi-transparent FROCs that can both transmit and reflect the same color\, akin to a beam splitter filter. This remarkable property is beyond the capabilities of conventional optical coatings. In the latter part of my presentation\, I will discuss recent theoretical and experimental efforts aimed at exploring optomechanics based on epsilon-near-zero materials5. \n \n[1] Lininger\, A.\, Hinczewski\, M.\, & Strangi\, G. “General Inverse Design of Layered Thin-Film Materials with Convolutional Neural Networks”.

SUMMARY:Seminar in Biochemistry\, Biophysics\, and Biodesign: John McGeehan\, Principal Scientist of Biochemical Engineering
DESCRIPTION:Following the discovery in a Japanese recycling \nfacility of a bacterium capable of breaking down the man-made \nplastic polyethylene terephthalate (PET)\, we turned our attention \ntowards uncovering the detailed workings of enzymes that can \nperform this remarkable reaction. Found in single-use drinks bottles\, \npackaging\, and clothing\, PET can take centuries to decompose and is \naccumulating in our environment at a staggering rate. Enzymes that \ncan digest PET\, and other highly polluting plastics\, into their original \nmonomer building blocks provides routes towards circular plastic \nrecycling. Working across broad scientific areas\, from microbiology \nfield studies searching for novel plastic-digesting bacteria\, through \nto biochemistry and structural biology combined with artificial \nintelligence\, we are engineering improved enzymes and accelerating \ntechnologies to help tackle our plastics crisis. John will provide an \nintroduction to this growing field and updates on the latest \ndevelopments from the NREL research team.

SUMMARY:Guest Speaker: Steve Eichhorn\, PhD
DESCRIPTION:Using Cellulose to Store and Harvest Energy\nAbstract: This talk will cover the use of cellulosic materials for the harvesting and storage of energy. The talk will cover the history of cellulosic materials used in both batteries and capacitors\, introducing the use of nanocellulose\, and carbon materials derived from this material for use as electrodes and also as the separators in batteries. Work carried out on supercapacitors will also be discussed\, and how things are progressing with the use of biomass for capacitive deionisation devices. Finally\, some very recent work on the combination of graphene and cellulose for the production of triboelectric nanogenerators will be introduced and discussed\, showing how it might be possible to have an all-cellulose/polymer device\, and potentially place such devices on clothing and other structures for the generation and storage of power. \nBio: Steve Eichhorn graduated with a bachelor’s degree in physics from the University of Leeds in 1993. He then went on to do a Master’s degree and PhD (1995-1998) at the University of Manchester Institute of Science and Technology (UMIST) in the Paper Science Department. Following that he carried out postdoctoral research under the supervision of Professor Bob Young FRS in the Department of Materials Science and Engineering (1999-2002). He was hired as a new lecturer in 2002 in the Materials Science department\, which then became the School of Materials in 2004 when UMIST merged with the Victoria University of Manchester. He was promoted to Senior Lecturer and Reader and then went to become Chair of Materials Science at the University of Exeter in 2011. At Exeter he built an activity around sustainable materials research\, and also took on leadership roles as a co-Director of an EPSRC funded doctoral training centre and he was the Head of Engineering (from 2014-2017). In September 2017 he moved to the University of Bristol and into the newly formed Bristol Composites Institute\, and was interim Head of School (for the CAME School of Engineering) in 2020. He has been awarded the Rosenhain Medal and Prize in 2012 from the Institute of Materials\, Minerals & Mining (IOM3) for his contributions to Materials Science\, the Hayashi Jisuke prize from the Japanese Cellulose Society (in 2017)\, the Swinburne Medal and Prize (IOM3) in 2020\, and was the Chair of the ACS’s Cellulose and Renewable Materials Division. He was also made a Fellow of the Division in the same year. In 2021 he was awarded an EPSRC ED&I fellowship on Biobased Composites. The ED&I programme of work has a specific emphasis on Black and Black heritage staff and students. \n

SUMMARY:Photonics Initiative Seminar: Jacob Khurgin
DESCRIPTION:Dr. Jacob Khurgin (Johns Hopkins University) \nCoherent Frequency Combs in Mid-Infrared and THz Produced By Self Frequency Modulated Quantum Cascade Lasers\nFor many applications Optical Frequency Combs (OFCs) require a high degree of temporal coherence and thus narrow linewidth1 as well as wide bandwidth (i.e. many spectral lines.  Commonly OFCs are generated in some nonlinear media from a monochromatic narrow linewidth laser sources or from a mode-locked laser pulses but in the all-important mid-infrared (MIR) and terahertz (THz) regions of spectrum OFCs can be generated intrinsically (i.e. without any intracavity mode-lockers) by the free-running quantum cascade lasers (QCLs) with high efficiency These combs do not look anything like conventional OFCs as the phases of each mode are different and in temporal domain the OFC is a combination of amplitude- and phase-modulated signals rather than a short pulse. Despite this fact the experimental evidence suggests that the linewidth of the QCL OFC is just as narrow as that of a QCL operating in the single mode. While universally acknowledged\, this observation is not fully understood.  In this work we rigorously prove the narrowness of the QCL OFC linewidth by deriving the expression for the Schawlow-Townes linewidth and obtain an analytical expression for the maximum potential bandwidth of the frequency modulated comb naturally occurring in free running QCL’s. The bandwidth is shown to critically depend on the flatness of the gain spectrum and the cavity length and less so on pump current. The results firmly establish that the performance of QCL frequency combs can be on par with combs generated by other means. \nExpanding Dynamic Range (Linearizing) of Electro Optic Modulators by All Optical Means\nAnalog photonic systems are crucial for expanding RF photonics applications and higher-order coherent digital systems. The increasing demand for high-performance RF photonic links in 5G and other applications necessitates highly linear transmitters. A key challenge is the inherent nonlinearity of Mach-Zehnder modulators (MZMs)\, which limits the spurious-free dynamic range (SFDR). Numerous MZM linearization techniques have been explored\, including electrical\, optical\, and mixed methods. Electrical linearization suffers from bandwidth limitations and high power consumption. Mixed methods\, often employing multiple modulators\, require precise control of numerous voltages and may not compensate for second harmonic distortion. In this talk I highlight the work on development of integrated rugged all-optical linear modulators using three different linearization schemes: (1) Ring Assistant MZI (RAMZI)\, (2) Grating Assisted MZI (GAMI) and (3) Combined Dual Output MZI. The modulators have been realized using Si\, III-V and LiNbO3 platforms and have show record high FDR results. \nBio –  Jacob B. Khurgin\, a professor of electrical and computer engineering\, is known for his diverse and eclectic research in the areas of optics\, electronics\, condensed matter physics\, and telecommunications. Khurgin earned his BS and MS in Optics from the Institute of Fine Mechanics and Optics in St. Petersburg\, Russia in 1977 and 1979\, respectively. He immigrated to the United States in 1980 and spent eight years working as a researcher at Philips Laboratories in New York. He earned a PhD in Electro-Physics from New York University in 1987 and joined Johns Hopkins in 1988. \nThis is an in-person seminar.

SUMMARY:Photonics Initiative Seminar: Marc Serra Garcia
DESCRIPTION:Dr. Marc Serra Garcia (AMOLF) \nPhysical computing in metamaterials\nAbstract – There is a significant range of physical phenomena—from nonlinear elasticity\, to symmetry\, noise\, topology\, and disorder — that are rarely utilized in traditional computing paradigms. Yet these phenomena can unlock new efficiencies\, by directly processing signals in their natural domain\, and by bypassing the traditional abstraction stack associated with digital CMOS technology. However\, building physical computers is challenging. Information processing tasks generally involve complex input-output relations\, thus requiring designs that are highly expressive; and for these designs\, the relation between function and structure is nontrivial\, complicating the simulation\, design\, and fabrication of devices. In my talk\, I will illustrate our journey towards using metamaterials for physical computing\, with two recent examples. First\, I will talk about our results in passive speech recognition\, where we leverage a phononic metamaterial to implement wake-up-word detection with zero standby power consumption. Second\, I will discuss our ongoing work in self-learning materials\, that autonomously adapt to improve their performance—driven by their ability to form long-term memories in response to examples and external feedback. \nBio – Dr. Marc Serra-Garcia is a Caltech (MS 2013) and ETH Zurich (Ph.D. 2017) trained aerospace engineer researching materials with improved mechanical properties. He was the technical co-founder of the startup TapTools\, focusing on the development of cost and time-efficient material testing devices for manufacturing\, aerospace and construction industries. \nThis is an in-person seminar.

SUMMARY:Photonics Initiative Seminar: Armando Genco
DESCRIPTION:Armando Genco (Politecnico di Milano) \nUltrafast dynamics of coherent exciton-polaritons in van der Waals semiconductor metasurfaces\nAbstract – Metasurfaces based on transition metal dichalcogenides (TMDs) have emerged as a promising platform for controlling light at the nanoscale due to their exceptional optical properties\, including strong excitonic responses and intrinsically high refractive index. Unlike traditional dielectric metasurfaces\, TMD-based platforms enable highly confined optical modes with minimal losses\, making them ideal for applications in nanophotonics. The high refractive index of TMDs plays a crucial role in supporting Mie-type resonances and facilitating the realization of bound states in the continuum (BICs)\, which exhibit theoretically infinite quality factors and extreme field localization. The interplay between BICs and TMD metasurfaces opens new avenues for enhancing light-matter interactions\, paving the way for efficient nonlinear optics\, lasing\, and quantum photonic devices. \nIn my talk\, I will discuss highly tunable optical metasurfaces composed of nanorod-type unit cells made of bulk WS2\, where excitons are strongly coupled to quasi-BIC modes forming polariton states at room temperature. I will first focus on the often-overlooked polarization-dependent angular dispersion of the resonant modes\, which we characterized across the entire momentum space using hyperspectral imaging. The photonic band structure plays a crucial role in shaping the nonlinear behavior and ultrafast dynamics of polaritons\, which we investigated through various pump-probe spectroscopy techniques. Leveraging high temporal resolution\, we tracked the coherence of strong light–matter coupling\, revealing pronounced oscillations in the pump-probe traces\, signature of polariton quantum beats.” \nBio – Dr. Armando Genco is an Assistant Professor at Politecnico di Milano (Italy) and an expert in optics and photonics. His research primarily explores light-matter interactions between excitons in quantum materials and photons confined in optical micro- and nanoresonators\, both in static and transient conditions. \nThis is an in-person seminar.  If you opt to join via zoom use meeting ID 880 6343 0208  Passcode 553685

SUMMARY:Photonics Initiative Seminar: Arthur D. Yaghjian
DESCRIPTION:Dr. Arthur D. Yaghjian (Electromagnetics Research) \nRobust Field-Based Antenna Quality Factor\nAbstract – New field-based quality factors Q(ω) are derived for antennas with known fields produced by an input current. These Q(ω) are remarkably robust because they equal the input-impedance bandwidth quality factor QZ(ω) when the input impedance is available. Like QZ(ω)\, the field-based Q(ω) is independent of the choice of origin of the antenna fields and is impervious to extra lengths of transmission lines and surplus reactances. These robust field-based quality factors are used to derive new lower bounds on the quality factors (upper bounds on the bandwidths) of spherical-mode antennas that improve upon the previous Chu/(Collin-Rothschild) lower bounds for spherical modes. \nBio –  Dr. Arthur D. Yaghjian received the B.S.\, M.S.\, and Ph.D. degrees in electrical engineering from Brown University in 1964\, 1966\, and 1969\, and an Honorary Doctorate from the Technical University of Denmark in 2020. After teaching for a year\, he joined the research staff of the National Institute of Standards and Technology (NIST)\, Boulder\, CO in 1971 and transferred in 1983 to the Air Force Research Laboratories\, Bedford\, MA until 1996 when he became an independent researcher. His early research at NIST helped pioneer the development of probe-corrected near-field antenna measurements for accurately characterizing modern antennas in both the frequency and time domains. More recently\, he has extended the spherical-wave near-field antenna theory to the rigorous analysis of the partially coherent fields radiated by the sun and other stars. His research in electromagnetic theory has led to the fundamental determination of electromagnetic fields in spatially dispersive as well as temporally dispersive natural materials and metamaterials. He has derived the definitive microscopic and macroscopic force and energy expressions for both diamagnetic and paramagnetic media. He has contributed significantly to the determination and fundamental understanding of the classical equations of motion of accelerated charged particles. In the area of high-frequency diffraction\, he and Robert Shore obtained convenient robust expressions for incremental length diffraction coefficients that are currently used to predict bistatic scattering and reflector antenna performance in commercial high-frequency computer codes. His work with Steven Best on the fundamental characterization of antennas\, including the determination of the upper bounds on the bandwidth of complex antennas\, has had a major impact on the research and development of modern electrically small antennas. He holds the patent on supergain electrically small antennas. He is an IEEE Life Fellow and has been an IEEE-APS Distinguished Lecturer. He has received the IEEE Electromagnetics award\, the IEEE-APS Distinguished Achievement award\, four IEEE Schelkunoff prize paper awards\, and has written two well-referenced books\, one co-authored with Thorkild Hansen. \nThis is an in-person seminar.  If you opt to join via zoom use meeting ID 595 955 6744 Passcode 842444

SUMMARY:Interdisciplinary Seminar Series featuring Associate Professor Dr. Xi Chen
DESCRIPTION:EvapoFlex: Water-responsive Materials for Evaporation Energy Harvesting \nMany important physiological functions of living organisms (e.g.\, plant seed dispersal\, bacterial spore activation) rely on water-responsive (WR) materials that mechanically deform in response to changes in relative humidity. Recently\, biological WR materials have been shown to generate significantly higher energy actuation compared to all known animal muscles and mechanical actuators. These materials have enabled the development of evaporation energy harvesting generators that operate autonomously when placed at a suitable air-water vapor interface. Theoretical and physical studies suggest that these devices are highly scalable and could produce power densities comparable to current solar and wind farms\, while mitigating the intermittency issue that is often experienced by these renewable energy sources. \nTo transform the field of WR materials and their associated evaporation energy harvesting techniques\, we employ a convergent and deeply interdisciplinary approach. We term this overall effort EvapoFlex. We expect that EvapoFlex will establish a comprehensive framework to harness the ubiquitous and untapped energy embodied within natural and industrial evaporative water sources for actuation\, renewable energy conversion\, and environmental protection. We see our energy production system as highly unorthodox yet promising\, and admittedly a high-risk/high-reward enterprise. If successful\, EvapoFlex will lead to a previously unrecognized clean energy resource of water evaporation with power production potential comparable to that of current solar and wind farms\, but at a much lower economic and resource cost\, few intermittency issues\, and with a high potential for public acceptance.

SUMMARY:Seminar in Biochemistry\, Biophysics\, and Biodesign: Stephen D. Fried\, Assistant Professor Department of Chemistry
DESCRIPTION:Abstract: Recent advances in artificial intelligence have addressed a long-standing question in protein biophysics: What is the relationship between a protein’s primary sequence and its native three-dimensional structure? On the other hand\, the process by biosynthesis or following their denaturation is perilous\, complex\, and much less predictable. Many proteins misfold\, a process which can sometimes be reverted (but not always) through chaperones\, and is moreover associated with a wide range of ailments\, particularly neurodegenerative diseases. My lab became interested in delineating which (kinds of) proteins are capable of refolding into their native conformations spontaneously versus which ones require chaperone assistance. To do so\, we developed limited proteolysis mass spectrometry (LiP-MS) methods\, a structural proteomic approach that can interrogate protein conformation and misfolding on the proteome scale. These experiments provide a holistic view of what properties facilitate refoldability and have highlighted an important and unexpected role for intrinsically disordered regions. In this talk\, I want to emphasize that despite great strides in AI-based tools\, there are still many surprises for this field. For instance\, we have recently discovered a case of a protein whose misfolded form is even more kinetically stable than its native form. We also have documented a case of a protein whose folding is obstructed (rather than promoted) by the chaperone\, Trigger Factor. Though it remains to be seen how widespread these “unusual” cases are\, these results highlight the importance of us continuing to think deeply about protein folding with the spirit of curiosity and exploration\, and showcases the power of emerging proteome-wide experimental approaches. \n  \nPlease use this link to access Zoom. \nMeeting ID: 914 4825 7859\nPasscode: asrc+ccny

In the second part\, I will discuss heterogeneously integrated photonic crystal optoelectronic devices based on the micro transfer printing process\, including high-speed photonic crystal spatial light modulators and monolayer graphene total absorption in critically coupled photonic crystal cavities and designs toward high speed reconfigurable intelligent surfaces. \nWeidong Zhou is a Distinguished University Professor and Janet and Mike Greene Professor at the University of Texas at Arlington (UTA). He obtained BS and ME degrees from Tsinghua University\, China\, and a Ph.D. degree from University of Michigan\, Ann Arbor. After graduation\, he spent three years at CIENA Corporation working on optical transceiver modules and subsystems for optical communication systems. Prof. Zhou and his group have made significant contributions to semiconductor heterogeneously integrated photonic crystal membrane photonics\, especially photonic crystal lasers\, modulators\, and sensors\, for integrated silicon photonics and flexible optoelectronics. He has published over 400 journal papers and conference presentations\, including many papers published in high-impact journals such as Nature Photonics\, Nature Communications\, Nature Biomedical Engineering\, etc. He has also delivered over 100 invited conference talks. Dr. Zhou is a fellow of SPIE\, a fellow of Optica\, a senior member of IEEE\, and a member of APS and AAAS. He is the Director of UTA Photonics Center. \nThis is an in-person seminar.

SUMMARY:Seminar in Biochemistry\, Biophysics\, and Biodesign: Benjamin Schuster\, Assistant Professor Department of Chemistry and Biochemical Engineering
DESCRIPTION:Negative noodles\, and positive ones too: Biophysics and bioengineering of intrinsically disordered proteins \nIntrinsically disordered proteins (IDPs) do not fold into a fixed three-dimensional structure\, yet they play important roles in biology. For instance\, many IDPs phase separate into biomolecular condensates that function as membrane-less organelles in cells. If IDPs are somewhat like a cooked noodle\, then condensates are roughly akin to a ball of cooked spaghetti\, or perhaps pasta primavera. In this talk\, I will describe three recent studies from my lab and collaborators\, relating to the biophysics and bioengineering of these “noodles.” I will begin by discussing engineered IDPs (including highly charged sequences) that have provided new insights into the molecular grammar of protein phase separation. Second\, I will present biophysical insights into the role of protein condensation in the SARS-CoV-2 viral lifecycle\, focusing on how phosphorylation within a cationic disordered\nregion toggles the material state and function of nucleocapsid protein condensates. Third\, I will demonstrate how nanoparticle surface engineering allowed us to achieve controlled and orthogonal partitioning of large particles into IDP condensates. Together\, these vignettes help link IDP sequence\, phase behavior\, rheology\, and function\, with implications for condensate biology and therapeutic targeting of condensates in disease.
