Abstract

We investigate the photoresponse linearity and speed of an InP-based asymmetric dual-grating-gate high-electron-mobility transistor (ADGG HEMT) terahertz (THz) plasmonic detector with respect to the incident THz signal intensity. We experimentally demonstrate that the ADGG HEMT has a high linearity up to 8 mW incident power, which is three-orders-of-magnitudes higher than commercially available Schottky-barrier diode detectors, with the internal current responsivity of 1.3 A/W.
