Multiquantum-well detection of nanosecond far-infrared superradiant pulses at temperatures above 77 K

A lightly doped GaAs/(Ga,Al)As multiquantum-well sample is shown to be a fast detector of 2-5-ns wide far-infrared (FIR) pulses in the wavelength range from 100 to 500 microns. The conditions for optimum bias, sign of the photosignal, and non-linearity in the low-temperature current-voltage curve su...
