Photonics Initiative Seminar: Ventsislav K. Valev

March 25, 2026 @ 11:00 am

Speaker: Ventsislav K. Valev Title: Polarization-Resolved Nonlinear Optical Activity in Scattering Abstract:  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 Read More

Heterogeneously Integrated Photonic Systems for Quantum Science

March 20, 2026 @ 11:00 am

Metasurfaces, subwavelength optical interfaces that control the amplitude, phase, and polarization of light, have transformed flat optics, yet extending this control from static wavefront shaping to dynamic, real-time manipulation remains a central challenge. In this talk, scientist Prasad P. Iyer will show how his lab's research addresses this challenge across increasing levels of complexity: from Read More
