Abstract

A new simple form of a rib-waveguide polarizer is proposed and investigated. The cladding consists of a dielectric multilayer based on Si and SiO2; the core is a single-mode MO (magnetooptic) channel waveguide in Ce-substituted Yttrium Iron Garnet (YIG). The TM-passing property of the anisotropic cover filters out the unwanted polarization. The authors first develop a modal analysis of the rib waveguide and then perform a full-wave modeling of the polarizer by means of the transmission-line matrix integral equation (TLMIE) method. The TLMIE is an efficient three-dimensional (3-D) hybrid technique that combines the advantages of the numerical transmission-line matrix (TLM) method in dense finite regions, and those of the analytical Green's functions where available. The TLMIE method validates the modal analysis, yields an accurate physical insight of the polarization selection, and, it provides a tool for the optimization of the device.
