THEORY OF OPTICAL WAVE COUPLING IN THE PRESENCE OF MAGNETOSTATIC SURFACE WAVES

The general expression of magneto-optical permittivity tensor including the Faraday and Cotton-Mouton effects is derived and the coupled wave equations for the optical modes propagating in an arbitrary direction with respect to the magnetostatic surface wave are obtained. The optical multimode coupled wave equations will reduce to the bi-mode ones in the phase-matching conditions. The behaviors of four types of important optical bi-mode coupling are discussed and some new results are obtained. In the limits of α= 0 and π/2, all results obtained reduce to those reported in the literature.
