Abstract :
This paper presents the effect of optical mixing in zero-bias InGaAs Schottky detectors at THz frequencies. The excitation of ultrafast carriers by illumination with two 1.5 mum laser beams is verified. This proves the suitability of the diode for phase sensitive detection in CW THz systems.
