A fast terahertz (THz) continuous-wave detector based on weakly ionized plasma is developed. Its response time can be less than a microsecond according to calculation. By comparing with a Schottky diode in a THz interferometer, we illustrated that our detector has faster response time, linear responsivity, and higher signal-to-noise ratio.
