The RLE 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.
Investigations:
High-performance THz quantum-cascade lasers
Novel emitters with high beam qualities
Tunable THz wire lasers
Real-time THz imaging
Time-domain study (TDS) of THz quantum structures
MEMS-based arrays of millimeter receivers
The group is led by Professor Qing Hu
