Abstract :
Schottky diodes have been used for submillimeter , heterodyne detection and harmonic mixing. Using a carcinotron local oscillator at 890 mu m, sensitive detectors of optically pumped lasers have been demonstrated up to fifth harmonic mixing at 1757.5 GHz. The measured noise equivalent power (NEP) in fundamental mixing is approximately 10-16 W/Hz.
