Abstract

An ultracompact polarization beam splitter (PBS) is proposed based on an asymmetrical directional coupler consisting of a silicon hybrid plasmonic waveguide (HPW) and a silicon nanowire. The widths of the two coupling waveguides are chosen so that the phase-matching condition is satisfied for TE polarization only while the phase mismatch is significant for TM polarization. A sharply bent silicon HPW is connected at the thru port to play the role of polarizer by utilizing its polarization-dependent loss. With the present principle, the designed PBS has a footprint as small as only 1.9μm×3.7μm, which is the shortest PBS reported until now, even when large waveguide dimensions (e.g., the waveguide widths w1,2=300nm and the gap width wgap=200nm) are chosen to simplify the fabrication process. The numerical simulations show that the designed PBS has a very broad band (120nm) with an extinction ratio >12dB and a large fabrication tolerance to allow a waveguide width variation of ±30nm.
