Research output: Contribution to journalArticlepeer-review


The terahertz (THz) radiation emitted from a double quantum well is investigated and optimized. Exploiting the phenomenon of quantum stochastic resonance (whereby the oscillation amplitude of a dissipative two-level system exhibits at low temperatures a non-monotonic response with respect to the parameters of a monochromatic external field or the strength of dissipation) to drive a series of identical double quantum wells, it is shown that the coherence properties of the emitted THz radiation can be boosted significantly.
