Analysis of anisotropic optical waveguides using a three-dimensional finite difference method

Abstract

The model describing excitation and distribution of electromagnetic waves in an anisotropic optical waveguide in the three-dimensional case is presented in this paper. The finite difference method (FDM) has been employed for the Maxwell equation discretization for a random anisotropic medium. The resulting system of linear algebraic equations for the electric-field components in an inhomogeneous anisotropic medium is solved by the method of biconjugate gradient.
