Our lab works on Silicon Photonics with special emphasis on integration of on-chip light sources. Leveraging the state of the art nanofabrication technology and interdisciplinary cooperation, we develop photonic integrated circuits that can be applied for data communications, biosensors/bioimaging, energy harvesting, machine vision, and quantum information processing.

Our invited talk at PIERS 2022 and CLEO 2022 reviewed recent stride that has been made in individuals QD devices grown on Si, and several paths to be explored for active-passive coupling and co-Integration of QD lasers to the rest parts of Si photonics.
Direct epitaxial integration of III-V optoelectronic devices on Si offers a substantial manufacturing cost and scalability advantage over heterogeneous integration via wafer bonding.
Heterogeneous integration bonds unpatterned III-V thin films to silicon wafers at the early- to mid-stages with a coarse alignment, and then define devices lithographically on the full wafer scale.
From the system-level, we develop photonic integrated circuits with on-chip lasers for applications of optical communications and interconnects, optical phased array-based LiDAR, sensors for chemical and biological analysis, integrated qu
From the device-level, different routes taken in integrating on-chip lasers will be explored from different material systems to the chosen integration methodologies: monolithic integration and heterogeneous integration
By light confinement in small volumes with resonant recirculation, microcavity lasers promise to complement the rise of Si photonics by populating these chips with sma
