Bragg waveguide of rectangular cross-section

Abstract

A method for calculating parameters of rectangular waveguides using separation of variables is presented. The method makes it possible to calculate multilayer Bragg waveguides with an arbitrary number of layers and an arbitrary composition as photonic crystal structures with defect. A result of the numerical calculation of the dispersion diagram of such a structure is given. This result is in good agreement with the earlier published data on the study of similar structures.
