Ultracompact Polarization Beam Splitter on Multi-Micron Silicon Photonics

We propose ultracompact polarization beam splitter using Brewster's angled trenches on multi-micron silicon photonics. Extinction ratio of 15 dB and insertion loss below 0.5 dB are obtained over the C band with
$30\times 30\ \mu m^{2}$
