Paper Abstract

We proposed an effective index perturbation method to investigate the intrinsic characteristics of three-dimensional photonic-crystal-slab based microcavity with two-dimensional numerical simulation tools such as two-dimensional finite-difference time-domain (2D-FDTD) and plane-wave expansion (2D-PWE) techniques, for reduced computational requirements and fast design feedback. Less than 2% computational error in predicting cavity spectral locations was obtained for two widely used single defect and line defect air hole photonic crystal cavities, by adjusting the effective index to match the dielectric band edge for donor-like defect mode. The correlation between the modified effective index and the cavity (lasing) mode with the highest quality factor Q offers an efficient tool in the design of defect mode based photonic crystal microcavities.
