Venue: S. V. Narasaiah Auditorium, IAP Department.
We are delighted to invite you to the upcoming IAP-API Joint Colloquium, featuring a talk by Prof. Yuri Kivshar from the Australian National University.
Abstract
In this talk, I will focus on the recent progress in chiral metaphotonics. Chiral metasurfaces promise to become invaluable tools capable of controlling structured light required for chiral biosensing, chiral photochemistry, and chiral quantum photonics. I will discuss chiral bound states in the continuum and chiral lasing, as well as several approaches to control chiral response of resonant metasurfaces via the interplay of lattice symmetries and meta-atom geometry. I will also mention the generation and ultrafast control of nonlinear chiral response in resonant optical systems, when nonlinear resonant generation of circularly polarized light from achiral dielectric metasurfaces becomes sensitive to the linear polarization of the fundamental wave, and a resonant metasurface can produce light with arbitrary degree of nonlinear chirality. I believe these results promise to enrich our understanding of nonlinear chiral processes and their ultrafast manipulation with resonant photonic structures.
Speaker’s Bio:
Prof. Yuri Kivshar is a Distinguished Professor and Head of the Nonlinear Physics Centre at the Australian National University (ANU), Canberra, and Research Director at the International Research Centre for Nanophotonics and Metamaterials, ITMO University, St. Petersburg, Russia. He received his Ph.D. in 1984 from Kharkov, Ukraine. After leaving the Soviet Union in 1989 and holding several visiting positions in Europe, he settled in Australia in 1993. His research spans nonlinear physics, metamaterials, and nanophotonics. He is renowned for pioneering work on solitons and has made foundational contributions to self-focusing effects, metamaterials, dielectric nano-antennas, topological insulators, optical signal processing, and optical communications. Prof. Kivshar is a Fellow of the Australian Academy of Science (since 2002), as well as a Fellow of Optica, APS, SPIE, and IOP. He has received numerous prestigious awards, most recently the 2022 Max Born Award and the 2025 ZEISS Research Award (Germany).
High Tea: 11:30AM-12:00PM.
