Abstract

A wavequide isolator using a 490-wavequide Faraday rotator and two fibre-optic polarizing filters as a polarizer and an analizer are simulated using the anisotropic three-dimensional RPM (beam propagation method). TE-TM-couplinq in a trapezoidal YIG-waveguide including coupling between guided wavequide modes are shown in different propagation planes. Besides the different development of TE-TM-coupling, which can be noticed between 45° to 115° to 45° Faraday rotation, changing of xy-intensity profiles at these points can he seen. The different behaviour of TE- and TM-fields in a fibre-optic polarization filter is calculated and depicted.
