Deterministic generation of bright single resonance fluorescence photons from a Purcell-enhanced quantum dot-micropillar system

Abstract

We report on the observation of bright emission of single photons under pulsed resonance fluorescence conditions from a single quantum dot (QD) in a micropillar cavity. The brightness of the QD fluorescence is greatly enhanced via the coupling to the fundamental mode of a micropillar, allowing us to determine a single photon extraction efficiency of $(20.7\pm 0.8)\%$ per linear polarization basis. This yields an overall extraction efficiency of $(41.4\pm 1.5)\%$ in our device. We observe the first Rabi-oscillation in a weakly coupled quantum dot-micropillar system under coherent pulsed optical excitation, which enables us to deterministically populate the excited QD state. In this configuration, we probe the single photon statistics of the device yielding $g^{(2)}(0)=0.072\pm 0.011$ at a QD-cavity detuning of $75\mu$eV.
