Paper Abstract

The propagation modes in a five-layer magnetooptical waveguide have been calculated as a function of the permeability and permitivity tensors of the material. TE-TM mode conversion caused by magnetic linear birrefringence has been studied for a plane magnetooptic wave guide consisting in a three-layer thin film epitaxially grown on a substrate and placed in the air, where the active element corresponds to the top layer. This structure makes it possible to obtain single mode propagation and mode conversion between different modes, which is of great interest in the making of optical devices (1). A relation between the thickness of the active layer and the width and refraction indexes of the intermediate layers in order to obtain single mode conversion has been established. Calculations were performed for wavelenghts of 1.152 μm.
