WELCOME

The Mid-Infrared Photonics group is a research group affiliated with the Micro and Nanotechnology Lab (MNTL) at the University of Illinois Urbana Champaign.  Our group studies mid-infrared (mid-IR) emitters, detectors, and photonic devices for applications in Defense and Security, Sensing, and Communications.

Please use this website to learn more about our lab and our research.  If you have any questions about the group, the Micro and Nanotechnology Lab, or the UIUC ECE Department, feel free to get in touch!
