Local Density of Optical States of an Asymmetric Waveguide Grating at Photonic Band Gap Resonant Wavelength

Abstract

We have investigated the characteristics of local density of optical states (LOOS) at photonic band gap resonant wavelength of an asymmetric waveguide grating based on Green's function formulation. It is found that the LOOS of the considered structure exhibits different characteristics in its localization between the upper and lower resonant wavelengths of the corresponding photonic band gap edges.
