Dynamics of the non-classical light from a single solid-state quantum emitter

We measure the dynamics of a non-classical optical field using two-time second-order correlations in conjunction with pulsed excitation. The technique quantifies single-photon purity and coherence during the excitation-relaxation cycle of an emitter, which is illustrated here using a quantum dot. We observe that photons detected early in the cycle have reduced single-photon purity and coherence compared to those detected later. Rate equation modeling describes the single-photon purity dynamics and indicates that the coherence dynamics are due not only to decoherence processes but also jitter in the exciton capture time.
