Summary:

Dr. Qing Li is an Assistant Professor in the ECE department of Carnegie Mellon University. He received his Ph.D. from Georgia Institute of Technology, with his doctoral research focused on developing optical signal processing technologies in both silicon and silicon nitride platforms. He then worked as a CNST/UMD postdoctoral researcher in National Institute of Standards and Technology, where he developed techniques for chip-scale quantum frequency conversion, octave-spanning microresonator frequency combs for optical frequency synthesis, and photonic interfaces for interrogating rubidium atomic systems. His current research interests include the study of nonlinear optical processes and quantum information science using nanophotonics.

The general research interest of the group is to study light and matter interactions that can be realized in an integrated photonics platform. One particular focus is on the nonlinear aspects of such interactions, which is a key enabling factor of many photonic technologies. In addition, it plays an increasingly important role in emerging fields such as quantum information processing and quantum computing. Using advanced nanofabrication and optical designs, the group aims to develop novel photonic materials/devices on the chip scale for classical and quantum information processing.
