Abstract

A theoretical analysis of the electronic interaction with an intense electromagnetic field in a two-level asymmetrical quantum dot is presented. As a consequence of a strong light-matter coupling in such a system, dipole radiation at the Rabi frequency turns out to be possible. Since the Rabi frequency is controlled by the strength of the coupling electromagnetic field, the effect can serve to provide frequency-tuned parametric amplification and generation of electromagnetic waves. The manifestation of the effect is discussed for group III nitride quantum dots. Terahertz emission from arrays of such quantum dots is shown to be experimentally observable.
