Outline of Final Research Achievements

Silicon photonics has the potential to provide high-density signal transmission for interconnection in a datacenter. Recently, multilayered three-dimensional Si photonics integrated circuits (Si-PICs) have been researched to enhance circuit integration capacity and for partial waveguide bridges to reduce the loss of the numerous waveguide crossings. In this research, I proposed a compact Si interlayer polarization beam splitter (PBS) and a Si interlayer optical switch that are based on a crystalline Si (c-Si) and hydrogenated amorphous Si (a-Si:H) vertical asymmetrical directional coupler.The device with a 260-nm × 220-nm and a 340-nm × 200-nm waveguides operates in a broadband, with small insertion loss and crosstalk. The device is also robust in terms of alignment error between the vertical waveguides. Totally, the proposed device seems to be feasible.
