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. © 2006 Wiley Periodicals, Inc.
