In-plane coupling into circular-grating resonators for all-optical switching
Abstract
This paper addresses the issue of in-plane coupling into and out of circular-grating resonators with optical waveguides for all-optical switching applications. Two different designs are proposed: the first design consists in directly accessing the cavity with the waveguides. The second design is based on optimization with an evolutionary algorithm that randomly reshapes the gratings along the waveguides. Passive linear simulations for both approaches are performed with the finite-elements method, and the results will be presented. © 2006 IEEE.
