Silicon-on-insulator (SOI) nanowire provides a very promising way to realize the future large-scale nano-photonic
integrated circuits because of the CMOS compatibility and the ability for ultrasharp bending. The giant birefringence of
SOI nanowires makes on-chip polarization handling become very important and useful for many applications, like
polarization-transparent silicon photonics, coherent optical communications, and on-chip quantum photonics. In this
paper, our recent work on on-chip polarization handling is reviewed and summarized, including polarization-beam
splitters, polarization rotators, as well as polarization splitter rotators.
