Abstract

GaAs Schottky barrier diodes with subrnicron anode diameter and high epitaxial layer doping were used as mixer up to 2.5THz. First, mixer performance was investigated measuring system noise temperature versus local oscillator power at different frequencies. Second, two lasers were taken as local oscillator and signal, respectively. Signals at the difference frequency and at two higher harmonics were generated. The power of the mixing signal was measured as a function of bias current. The behaviour of the higher harmonics was unusual. The extreme case was a sharp dip of more than 20 dB and a 3 dB width of only 30 μA.
