Abstract

Photon correlations in the emission of a resonantly driven quantum dot are investigated, accounting for the influence of the solid-state phonon environment. An analytical expression is derived for the second-order fluorescence intensity correlation function, from which regimes of correlated and uncorrelated photon emission are predicted as the driving field is varied. Experiments to investigate this effect would provide valuable insight into quantum dot carrier-phonon dynamics and are feasible with current technology.
