• Based on a transverse electric (TE)/transverse magnetic (TM) polarization diversity waveguide, we theoretically propose a TE-pass/TM-stop polarizer by etching a polarization dependent Bragg grating into the oxide layer of a silicon/thin SiO 2 gap/metal cap hybrid plasmonic waveguide. The simulation results indicate that the device is characterized by high TE-transmission and large TM-reflection levels in a wide waveband from 1.48 to 1.7 μm combined with an excellent compactness (length less than 5 μm). Transmission and reflection extinction ratio are both larger than 17.1 dB in the 1.48-1.64 μm wavelength range, while losses are smaller than 1.36 and 0.69 dB for the TE and TM modes, respectively.
