Integrated Polarization Diversity Devices

초록

Integrated polarization diversity devices, such as polarization beam splitter (PBS), polarization rotator (PR), and polarizer, are very important in silicon (Si)-based photonic integrated circuits (PICs). An integrated PBS based on a Si bridged-waveguide directional coupler, an integrated PR formed with an asymmetric Si waveguide having an internal trench, and an integrated TM-mode pass filter based on one-dimensional photonic crystal waveguide are introduced, and experimentally demonstrated results are reported.
