Modal analysis of multilayer planar lossy anisotropic optical waveguides

摘要

A systematic rigorous matrix method based on generalized transmission line (TL) modelling for the full-vectorial analysis of the guided modes of multilayer planar lossy anisotropic optical waveguides is developed. By means of the proposed method, complex propagation constants and mode field distributions of the propagating modes of planar waveguides with an arbitrary finite number of layers made of arbitrarily oriented anisotropic media are determined. The mode coupling and conversion phenomenon in a biaxial slab waveguide is demonstrated and a mode labelling scheme based on the polarization of the allowable plane waves in anisotropic media is proposed.
