Abstract
We report our investigation on low-temperature-grown GaAs THz photomixers using two different kind of antennas: silicon lens coupled spiral antenna and transverse electromagnetic horn antenna. We demonstrate that the horn radiates more power than the spiral above 600 GHz and at 2 THz the improvement is about a decade.
