Paper Abstract

We report on experiments where a single quantum dot is strongly coupled to a high-Q mode of a micropillar cavity. Photon correlation measurements confirm that the observed avoided crossing originates from strong coupling of a single quantum dot to the cavity mode. Cross-correlations between the cavity mode and the spectrally detuned quantum dot enabled us to assign the unexpected strong cavity emission to a coupling with the single quantum dot. The coupled quantum dot-microcavity system displays an Purcell factor of 61 and represents a single-photon source with an efficiency of 97%.
