From Nanoscale Light Sources to Photonic Integrated Circuits

A crucial yet unavailable component in high-performance photonic integrated circuits (ICs) and other chip-scale photonic systems is an on-chip light source that is efficient, economical, silicon-compatible, and electronically addressable. In this talk, I will cover several types of on-chip light sources, including III-V nanoLEDs and topologically protected microlasers, perovskite microlasers and luminescent hyperbolic metamaterials, as well as perovskite photodetectors. I will further discuss emerging applications achievable with these materials and devices, such as neuromorphic photonic computing systems.

Qing Gu is an Associate Professor at North Carolina State University, holding a joint appointment between ECE and Physics. She received her B.S. degree from the University of British Columbia, Canada in 2008, and her Ph.D. degree from the University of California, San Diego in 2014, both in Electrical Engineering. Prior to joining North Carolina State University, she was an Assistant Professor at the University of Texas at Dallas from 2016 to 2021. Her research activities include the experimental realization of quantum-inspired nanophotonic semiconductor light sources using emerging materials or novel cavity configurations, active and topological hyperbolic metamaterials, and perovskite optoelectronics. She is the author of the book “Semiconductor Nanolasers” by Cambridge University Press, published in 2017. She is a recipient of the ARO Young Investigator Award and NSF CAREER award.

Distinguished Speaker Colloquium

Created and hosted by the NC State Department of Electrical and Computer Engineering, the ECE Distinguished Speaker Colloquium is our flagship seminar series, featuring presentations from distinguished speakers drawn from both academia and industry who will address a wide variety of topics of interest to our community. Everyone is invited to attend, from undergraduates on up to faculty and industry friends -- the level of the presentations will be for non-specialists and accessible to students.
