title: Single-photon emitting diode based on a quantum dot in a micro-pillar.
abstract: We have fabricated a single-photon emitting diode based on a quantum dot in a micro-pillar cavity. By temperature tuning the dot emission into resonance with the cavity mode we see an enhancement in the collected photon intensity at 40 K. We perform autocorrelation measurements on the electroluminescence at fixed bias, observing photon anti-bunching. Due to the low resistance and capacitance of our device we can inject current pulses shorter than the lifetime of the quantum state, producing single-photon emission with g((2))(0) = 0.17.
