Electronic Terahertz Sensors

Tunable Terahertz Detectors for Non-Destructive Imaging

Our new generation terahertz sensors for non-destructive and contactless sensing applications can detect and analyze target compounds through solid materials, such as walls, wood and glass. The sensor features an AlGaN/GAN HEMT oscillating plasmonic detector with tunable dual gate nanoparticle THz absorption layer. The detector surface absorbs low-energy THz radiation, which induces intraband transitions in the nanoparticle layer situated between the two gates on the sensing pixel. The THz detector is tuned to the specific THz frequencies and is ultra-sensitive with a higher resolution than standard sensors of its type.
