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.


Nanocalligraphy paper combines art with advanced nanolithography

Congratulations to Nikolaos Farmakidis from the Advanced Nanoscale Engineering group at Oxford for his new paper entitled, “Exploiting rotational asymmetry for sub-50 nm mechanical nanocalligraphy.” This novel approach to nanolithography enabled Nik and co-lead author Jacob Swett to create complex patterns at the nanoscale inspired by the artwork of calligraphy...
