Abstract :
We report on the fabrication and quasi-optical responsivity measurements of detectors of free-space terahertz radiation in a broad spectrum (0.18 - 0.72 THz). The detectors are modified compound-semiconductor heterostructure field-effect-transistors, coupled to integrated planar antennas.
