The detectors are fabricated from GaAs high-mobility heterostructure in the standard semiconductor cycle using conventional optical lithography. The imaging sensor is manufactured on a single wafer. That process ensures high homogeneity and reproducibility of the plasmonic detector parameters (pixel-to-pixel deviation responsivity is within 20-percent range). Each unit detector proved to have room-temperature responsivity up to 50 kV/W with read-out circuitry and noise equivalent power 1 nW/Hz^0.5 in the frequency range 10 GHz – 1 THz. The detection mechanism is based on transformation of incident THz radiation into two-dimensional electron system (2DES) plasma oscillation. Plasma wave is then rectified on the inhomogeneity of 2DES electron density in the defect region.

Terahertz optics
As part of a ready-made solution for terahertz imaging, Terasense offers TPX and PTFE lenses and optical systems, which operate in the THz range. Plastic plano-raised lenses are made of Polytetrafluoroethylene (Virgin White PTFE, Teflon®), which has a low dielectric constant of approximately 1.96 @ 520 GHz with an index of refraction of 1.4. The THz range can be communicated as the recurrence scope of 300 GHz to 10 THz or the wavelength scope of 30 μm to 1 mm.
