Abstract

We theoretically investigate a coherent optical spectroscopy of a strongly driven quantum dot without and with the coupling between exciton and phonons. In the absence of this coupling, we achieve the experimental results obtained by Xu et al. [Science 317, 929 (2007)]. However, while taking this coupling into account, we observe some new features in the probe absorption spectrum including two sharp phonon-induced sidebands. Our results also demonstrate that the lifetime of phonons will play an important role in this coherent spectroscopy.
