Abstract

Photonic crystal based microcavity structure with high quality factor (Q) and small mode volume is designed to make use of the semiconductor nonlinearities. Two and three-dimensional finite difference time domain calculations are performed, to study the dependence of Q on the defect size and shape and the position, shape and size of the nearest neighbor holes, to obtain the optimum structures. Structures are optimized to utilize semiconductor materials in the defect region to realize solid-state devices. The effect of nonlinearity in controlling the Q-factor is also reported.
