Optical polarization control devices,polarizer,rotator,and polarization beam splitter,Si photonic and heterogeneous platform

We demonstrate the polarization beam splitter with the polarization rotator based on the rib waveguide and the compact mode demultiplexer (size : 3.0 × 3.8 μm²) using mosaic-based structures designed by Bayesian DBS algorithm on Si-photonic platforms.
