Quanyong Lu received his doctoral degree from Institute of Semiconductors, Chinese Academy of Sciences in 2010. He went to Center for Quantum Devices, Northwestern University as postdoctoral researcher and then Research Assistant Professor from 2010 to 2020. He was a Senior RD-chip Engineer in Applied Optoelectronics Inc. in 2020-2021. He joined Beijing Academy of Quantum Information Sciences (BAQIS) in November 2021.

 

He has demonstrated the first continuous wave THz semiconductor source based on on-chip difference frequency generation, the first room temperature semiconductor THz comb, the highest power mid-IR single mode laser, and the highest power mid-IR laser array, and high bightness THz quantum cascade laser. His current research is focused on quantum light sources and systems, including quantum cascade lasers, frequency comb, terahertz laser sources,  and other quantum light sources.
