Abstract

We report on a room temperature detector of infrared/THz laser radiation allowing to measure the radiation polarization state with picosecond time resolution. The ellipticity of radiation is analyzed applying three photoelectric phenomena: circular photogalvanic effect, linear photogalvanic effect, and photon drag effect. Each of these effects is monitored by different detector units stacked together in one detector.
