Ultra-broadband high-performance polarizing beam splitter on silicon

A high-performance silicon-based polarizing beam splitter (PBS) is proposed and demonstrated experimentally by using an improved structure with cascaded bent directional couplers. The measured extinction ratio (ER) is >35dB and the excess losses (EL) is 20dB, >25dB and >30dB are ~135nm, ~95...
