Welcome to the Youngblood Photonics Lab at Pitt
Our research combines unique optoelectronic materials with scalable photonic circuits to create new platforms for low-latency machine learning, reconfigurable photonic devices, and precision biosensing. Key to our work is a fundamental understanding of light-matter interaction at the nanoscale and use of advanced nanofabrication techniques to address major challenges facing these disciplines. The following areas of research in our group are: 1) Programmable Photonic Devices and Architectures for Machine Learning; 2) Waveguide-Integrated Circuits for Biosensing; and 3) Waveguide-Integrated 2D Materials for High Performance Optoelectronics.News:
