Abstract

We propose a polarization beam splitter (PBS) based on a bridged silicon nanowaveguide directional coupler. The device is designed via 3D-FDTD simulation, and demonstrated experimentally. The measured polarization extinction ratio and the insertion loss of the PBS with 7.5-μm-long coupling length and 550 nm-wide bridged waveguides width are about 22 dB and 2 dB, respectively, for a TE-mode optical beam input.
