Abstract

We investigate the spontaneous emission by electrons traversing ballistically a superlattice in semiconducting heterostructures. It is found that for an injected current of 100 μA into a 5 × 20 μm² device there are about 5 × 10⁸/s infra-red photons emitted, mostly perpendicular to the electrons direction of motion. We also estimate the gain of the structure, and find that stimulated emission occurs when the threshold current density is of order 10⁴ A/cm².
