Abstract

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, IC-compatible, and electronically addressable. In this talk, I will cover several types of on-chip sources, including III-V nanoLEDs and topologically protected microlasers, perovskite microlasers and luminescent hyperbolic metamaterials, and III-N spintronic THz emitters. I will also discuss emerging applications of these metamaterials and devices, such as photonic neuromorphic networks.

Seminar Speaker Bio
Qing Gu is an Associate Professor at NC State with a joint appointment between ECE and Physics, and a member of the Carbon Electronics Cluster. 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 NC State, 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.
