Quantitative temperature characterization of nanocavity lasers 

Semiconductor micro- and nanocavity lasers have attracted much attention due to their high-quality factor (Q-factor), low threshold lasing and low power consumption, promoting them as excellent candidates for light sources in optical interconnects for large-scale integration. There is a general trend of downscaling laser cavity, but with high integration and energy density, significant thermal issue affects their operation. They are little explored in literature because of difficulties in obtaining quantitative measurements.

We present a quantitative thermal characterization of InP-on-Si micro- and nanocavity lasers using Raman. This research work combined simulation with experimental characterization, analyzed the thermal effects of nanocavities from steady-state to transient and from structure design to pumping strategy. The methods and findings are transferable to other types of nanophotonic devices and help the general understanding of the complex thermal behavior in nanodevices

Speaker

Dr. Pengyan Wen, IBM Research Europe, now Associate Professor at Tongji University, Shanghai, China
Dr. Wen has over ten years of experience in III-V lasers and photodetectors. During her PhD in Chinese Academy of Sciences, she was doing research on GaN-based lasers and reliability related issues, promoting their application in laser display and laser lighting. From March 2020 to February 2023, she worked as a Marie-Curie Fellow with Prof. Kirsten Moselund and Dr. Bernd Gotsmann at IBM Research Europe-Zurich, doing research on Si-based InP/InGaAs nanocavity lasers and photodetectors. She is currently an associate professor at Tongji University in Shanghai. Her research interests include III-V optoelectronic devices, electronic devices; especially on thermal, strain and defect related reliability issues
