Abstract

We describe a new full-vector finite difference method, based upon the transverse magnetic field components, for calculating the electromagnetic modes of anisotropic optical waveguides. Unlike earlier finite difference approaches, our method allows for the material axes to be arbitrarily oriented, as long as one of the principal axes coincides with the direction of propagation. We demonstrate the capabilities of the method by computing the modes of an off-axis poled anisotropic polymer waveguide and the circularly-polarized modes of a magnetooptical waveguide.
