Compact Broadband Rapid-Adiabatic Polarization Splitter- Rotators in a Monolithic Electronic-Photonic SOI Platform

We demonstrate a novel compact, ultra-broadband polarization splitter-rotator (PSR) based on a photonic magic-T and rapid adiabatic mode splitter (RAMS). Polarization cross-talk is 5 × length reduction over a conventional adiabatic PSR.
