A detailed experimental study of the low frequency (video) response of a quasioptical Schottky diode detector over the microwave and FIR wavelength range is presented. An optimization of the responsivity versus the bias current is proposed and a generalized curve of the saturation power versus the FIR wavelength is given. This curve defines for any antenna point-contact Schottky diode detector, suitable for FIR detection, the power range for a linear detector response. A simple method is also described to calculate the coupling efficiency of the laser radiation into the antenna reception pattern.read more

Generation of tunable pulsed microwave radiation by nonlinear interaction of Nd:YAG laser radiation in GaP crystals.
TL;DR: Pulsed microwave radiation in a tuning range from 10 to 30 GHz has been generated through the parametric interaction of two near-infrared pulses in GaP crystals at low temperatures by a Nd:YAG laser emitting simultaneously at two frequencies.

Theoretical and experimental responsivity of fir antenna coupled metal-insulator-metal detectors
S. Marchetti,P. Sandri,R. Simili +2 more
TL;DR: In this article, the authors report a complete theory of the metal-insulator-metal, antenna coupled, mm and sub-mm detectors, and the voltage-power responsivity is simply derived from the geometrical antenna proprieties and the electrical junction characteristics.
