Micro-ring lasers for integrated silicon photonics

The project aims to investigate compound semiconductor micro-ring lasers on silicon substrates using selective area growth to engineer the shape of the lasing cavity at the nano/micro-scale. This project will open up new doors to the industry since an integrated laser which is reliable, efficient and easily manufacturable is still elusive in Si photonics.

Nanowire infrared avalanche photodetectors towards single photon detection

This project aims to demonstrate semiconductor nanowire based infrared avalanche photodetectors (APDs) with ultra-high sensitivity towards single photon detection. By employing the advantages of their unique one-dimensional nanoscale geometry, the nanowire APDs can be engineered to different device architectures to achieve performance superior to their conventional counterparts. This will contribute to the development of next generation infrared photodetector technology enabling numerous emerging fields in modern transportation, communication, quantum computation and information processing.
