Topological Nanophotonics Based on Semiconductor Photonic Crystals
Hosted By: Integrated Photonics Technical Group
16 November 2021, 20:00 - 21:00
Join the Integrated Photonics Technical Group for this webinar featuring Satoshi Iwamoto from the University of Tokyo focused on topological photonics.
Topological photonics, an emerging field in photonics, offers a novel route for realizing photonic devices with unprecedented functionalities. Optical waveguides with topological protection can guide light robustly even in the presence of structural imperfections and/or sharp waveguide bends, which is highly attractive for integrated photonics. The use of semiconductor photonic crystals is a promising approach to realize such topological optical devices in integrated photonics platforms.
The webinar will start with a brief introduction of topological photonics, before discussing how to construct topological states of light in semiconductor photonic crystals. Prof. Iwamoto will provide an overview of the recent progress in topological nanophotonics based on semiconductor photonic crystals, including his recent works on topological slow light waveguides and topological nanocavities. Finally, the webinar will discuss future challenges in semiconductor topological nanophotonics.
