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.

New multifunctional optical memory published in Optica

Posted on January 10, 2025

Our collaborative work entitled “High-speed multifunctional photonic memory on a foundry-processed photonic platform” is now published in Optica! In this work, we demonstrate that both volatile fine-tuning and nonvolatile course-tuning of photonic devices can be achieved within a single device using a PN junction and low-loss phase-change materials. This can... [Read More]
