Thin-metal-clad waveguide polarizers: analysis and comparison with experiment

We present an analysis of a thin-metal-film in-line fiber polarizer and compare the results with experimentally observed TE- and TM-mode losses. It is shown that the analysis predicts reasonably well the experimentally observed behavior. The present analysis can be used as a design aid for obtaining initial design parameters such as buffer thickness, type of metal, metal thickness, and superstrate refractive index for such polarizer structures.
