Paper Abstract

An ultra-compact TE-pass polarizer with an ultra-broad band is proposed theoretically and demonstrated experimentally by utilizing a silicon hybrid plasmonic waveguide. The metal layer of the silicon hybrid plasmonic waveguide is designed to have an F-P cavity as well as a Bragg grating so that the TM-polarized light is reflected efficiently while the TE-polarized light goes through with very low loss. By utilizing the present structure with a metal Bragg grating, the designed TE-pass polarizer is with a size of as small as 0.5 × 3.1 μμm2 and the theoretical extinction ratio is as high as 15 dB over a broad band of >200 nm.
