ABOUT THIS WEBINAR
Two challenging problems of photonic device modeling are addressed in this talk: multiscale modeling and optimization. When it comes to modeling an optically large system with subwavelength features, a multiscale simulation scheme is required. In other words, a simulation tool should be able to provide both the interaction of light at subwavelength scale and the propagation of light over large distances.

Rustu Umut Tok of COMSOL first demonstrates a multiscale simulation scheme—a special type of multiphysics simulation—which combines full-wave and ray optics approaches. Tok then provides an overview on optimization, another important aspect of photonic device simulation, with an introduction to both gradient-based and derivative-free optimization approaches.
