Abstract

We present a microscopical model for the multiphonon assisted quantum emission from an externally excited semiconductor quantum dot. In the high driving field limit, our model predicts several strong coupling features, in particular, a phonon-assisted Mollow-triplet splitting and anticrossings between the Mollow sidebands and the phonon satellite peaks. The observed anticrossing scales with the effective LO-phonon coupling and can be used as a measure for the phonon coupling strength. Further, we investigate the non-Markovian temporal emission dynamics of the main and multiphonon assisted triplet structures.
