title: Generalized transverse Bragg waveguides.
abstract: A coupled-mode analysis of 2-D generalized transverse Bragg waveguides (GTBW) with tilted distributed Bragg reflectors is presented. As a result of the absence of inversion symmetry about a plane perpendicular to the guiding stripe, the modes supported by these guides are not separable into the familiar form of transverse standing wave and longitudinal traveling-wave components. This fundamental change in the modal description yields new and potentially useful guided-mode behavior. Expressions for the spatial distribution of the optical field, phase and group velocity, and the dispersion relation as well as applications of GTBW are presented.
