Abstract
A terahertz detector circuit can include a high electron mobility transistor (HEMT) having multiple gates that can be controlled by gate signals to generate a gate-induced modulation pattern in a two-dimensional electron gas (2DEG) of the HEMT. When the gate induced modulation pattern substantially matches a signal induced modulation pattern generated by an incident terahertz signal then a detection efficiency of the incident terahertz signal is improved. Accordingly, an electronically tunable THz detector with high efficiency can be realized. When these THz detectors are arranged in an array and electrically coupled, THz images and/or multi-spectral THz images may be generated.
