Compact Polarization Beam Splitter Based on a 3-Waveguide Directional Coupler with Broad Bandwidth Performance

In this paper, we propose a novel polarization beam splitter (PBS) based on a 3-waveguide directional coupler (DC) with a Si 3 N 4 -loaded horizonal slot waveguide as the bridge. The performance of the device can be further improved by adding a filter at the thru port.
