Photonics Initiative Seminar: Arthur D. Yaghjian

April 7, 2025 @ 11:00 am

Dr. Arthur D. Yaghjian (Electromagnetics Research) Robust Field-Based Antenna Quality Factor Abstract – 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) Read More

Photonics Initiative Seminar: Armando Genco

March 31, 2025 @ 11:00 am

Armando Genco (Politecnico di Milano) Ultrafast dynamics of coherent exciton-polaritons in van der Waals semiconductor metasurfaces Abstract - 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, Read More

Photonics Initiative Seminar: Marc Serra Garcia

March 28, 2025 @ 11:00 am

Dr. Marc Serra Garcia (AMOLF) Physical computing in metamaterials Abstract - 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 Read More

Photonics Initiative Seminar: Jacob Khurgin

March 27, 2025 @ 1:30 pm

Dr. Jacob Khurgin (Johns Hopkins University) Coherent Frequency Combs in Mid-Infrared and THz Produced By Self Frequency Modulated Quantum Cascade Lasers For 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 Read More

Photonics Initiative Seminar: Giuseppe Strangi

March 14, 2025 @ 11:00 am

Dr. Giuseppe Strangi (Case Western Reserve University) Thin-Film Photonics: Enabling Fano Resonances and Optomechanics Abstract – 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 Read More

Photonics Initiative Seminar: Mikhail Belkin

January 24, 2025 @ 11:00 am

Dr. Mikhail Belkin, Technical University of Munich (TUM) New Applications for Nonlinear Intersubband Polaritonic Metasurfaces: from beam shaping to THz generation Abstract - 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 Read More

Photonics Initiative Seminar: Giovanni Milione

January 21, 2025 @ 12:00 pm

Dr. Giovanni Milione NEC Laboratories America, Inc. Vector Beams and Space Division Multiplexing Abstract – In this talk, I will overview two areas of my research at NEC Laboratories America, Inc.: For 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 Read More
