Abstract

A substructuring approach for numerical optimization of photonic crystal devices is proposed and demonstrated. Specifically, we consider the matching of coupled cavity waveguides (CCW's) - known also as coupled resonators optical waveguides (CROWs) - to free space. In this approach, one separates a priori between the invariant main structure that consists most of the PhC and the CCW, and the substructure that consists of a small portion of the CCW and evolves along the optimization course. Specific examples of matching configurations with insertion loss as low as few percent are presented.
