Abstract
A structure of polarization beam splitter based on a symmetrical metal-cladding waveguide (SMCW) was demonstrated. The light beam energy can be coupled into the SMCW directly through free space without additional coupler. By introducing anisotropic material into the guided layer, different excitation conditions for transverse-electric and transverse-magnetic modes are obtained, which results in polarization-dependent reflection. The propagation loss that is mainly caused by the metal absorption is <2  dB.
