Paper Abstract

In most studies of 1D and 2D photonic crystals (PC) and photonic bandgap structures (PBG), the structures are considered to be invariant with respect to the remaining dimensions. If the PBG structure is to be incorporated into an optical waveguide, the inevitable refractive-index inhomogeneity used to create the waveguiding effect may detrimentally affect the behavior of the PBG. In this paper, such an influence is demonstrated by numerical modeling of a first-order waveguide Bragg Grating as a 1D PBG device. A condition for perfect spectral behavior of a waveguide PBG device is formulated and its validity is verified by numerical calculation of modal reflection and transmission spectra.
