THz detection circuits

FBH has identified the region between 1 - 6 THz as particularly interesting for focal plane THz cameras and THz spectroscopy systems utilizing plasmonic operation of GaN HEMT MMIC. Arrays of such detectors for a focal plane THz camera operating in the frequency range 1 - 2 THz have been realized and exhibit state-of-the-art performance at 560 GHz.
