Welcome to the Youngblood Photonics Lab at Pitt

Our research combines unique optoelectronic materials with nanophotonics to create new platforms for high-efficiency machine learning and high-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) Photonic Devices and Architectures for Machine Learning; 2) Waveguide-Integrated Nanoplasmonics for High Density Biosensing; and 3) Waveguide-Integrated 2D Materials for High Performance Optoelectronics.

Reconfigurable smart windows using phase-change materials

Our paper entitled, “Reconfigurable Low-Emissivity Optical Coating Using Ultrathin Phase Change Materials,” has been published in ACS Photonics! Unlike most smart window technology which either transmits or blocks both visible and infrared light from the sun, we modulate our window’s properties only in the infrared. This allows us to leave...
