Abstract

The superradiant character of submillimeter-wave emission from optically excited electronic Bloch oscillations in a GaAs/(Formula presented)(Formula presented)As superlattice is investigated by time-resolved terahertz emission spectroscopy. The intensity of the radiation and its decay time are studied as a function of the density of excited charge carriers. From the measured emission efficiency, the spatial amplitude of the charge oscillations is estimated.
