We develop THz detectors based on plasmonic and resistive effects in GaN-HEMT technology for frequencies up to 2500 GHz - as narrow-band and wideband THz detectors. We also realize high-performance THz detector arrays and THz camera systems with integrated read-out electronics. All these developments are based on FBH's GaN-HEMT microwave process. In cooperation with the Goethe-Leibniz-Terahertz-Center, we have developed THz detectors with record performance in the 500 GHz - 2500 GHz range with integrated antennas and monolithic arrays.
The THz detectors exhibit very high sensitivity and a record optical noise equivalent power (NEP) performance of 26 pW/√Hz at 500 GHz with a bandwidth of 1000 GHz for individual detectors and detecor arrays.
