The Millimeter-Wave and Terahertz Devices Group develops novel devices operating from millimeter-wave to THz frequencies, and explores system-level applications enabled by those devices. Specifically, the group is working on high-performance THz quantum cascade lasers based on intersubband transitions in quantum wells; ultrafast time- and phase-resolved study of dynamics in quantum structures; sensing and real-time imaging THz systems for a variety of applications including remote sensing, biomedical imaging, and security.
The group currently concentrates on the physics and development of semiconductor quantum devices, THz quantum cascade lasers, and real-time THz imaging and other system-level applications.

Research is investigating physical and engineering issues relevant to devices and systems operating in the under-utilized millimeter-wave, terahertz, and infrared frequencies. This frequency range has great potential for applications in remote sensing, spectroscopy, imaging, and communications.
