Variational Method for Anisotropic Dielectric Waveguides

Abstract

A novel stationary functional is introduced for the analysis of open dielectric waveguides with transverse and/or longitudinal anisotropy. The functional is applicable to arbitrary dielectric and anisotropic profiles. As an example it is applied for two types of anisotropic optical fibers, one with anisotropic core and isotropic cladding and the other with both core and cladding anisotropic.
