Waveguiding in thin films with quadratic magneto-optical medium

The waveguiding in thin planar structures with quadratic magneto-optical me dium is analysed. The permittivity tensor elements with quadratic magneto-o ptical constants are specified. From synchronous condition for guided modes in layered system with magnetic ordering the dispersion relation of wavegu ide is presented. The reflection coefficients for s-polarized light at tran sversal, longitudinal, and polar configurations as incidence angle function are described. The influence of quadratic magneto-optical effect on the re sonant character of the waveguiding term is described in detail. The theory covers the situation in which the optical response of the structure is lin ear in the amplitude of the incident wave.
