Our photonics research involves using light for applications including optical communications, medicine/biology, computing, and sensing.
Our projects involve design, modeling, and nanofabrication of lasers, in particular, Vertical Cavity Surface Emitting Lasers (VCSELs) and Semiconductor Ring Lasers (SRLs). We are developing new optical communication technologies with drastically enhanced performance enabling higher functionality systems. These are based on transistor lasers and optical injection locking.
We are also researching silicon photonic integrated circuits (PICs). We are developing nanophotonics devices to solve the communication bottle neck between the CPU and memory in computers. Nanophotonics allows one to integrate optics onto electronic chips to increase data communication. Our work currently focuses on designing passive structures (e.g. optical resonators, filters), as well as silicon modulators.
