Modeling Nonlinear Photonics in Dielectric Resonant Metasurfaces Using COMSOL® - Archived
Nonlinear photonics underpins a wide range of applications, such as optical sensing, light emission, and frequency conversion. Designing efficient nanophotonic devices requires an understanding of material properties and electromagnetic wave interactions, which can be effectively analyzed using the COMSOL Multiphysics® software.
In this webinar, Dr. Varun Raghunathan of the Indian Institute of Science (IISc) will present his work on all dielectric resonant metasurfaces for nonlinear photonic applications. He will discuss experimental studies on resonant enhancement of nonlinear optical processes using low-loss dielectric materials such as silicon and germanium, particularly in the infrared regime. He will also discuss modeling strategies in COMSOL Multiphysics® for understanding and optimizing the nonlinear optical performance of dielectric metasurfaces.
