Zusammenfassung:We report the experimental results for the polarizing properties of an optical coupler made of a single mode side-polished fiber and multimode metal-clad planar waveguide. The experimental results show that the large birefringence of a metal-clad planar waveguide facilitates the effective separation of TE and TM polarization in the spectral domain. Furthermore, through proper control of the planar waveguide parameters, the coupler can be used as either a TE-pass or TM-pass polarizer within a large spectral window (>130 nm). We present an approximated analytical method to calculate resonant wavelengths and demonstrate its validity experimentally.
