Paper Abstract

We demonstrate electrically pumped single-photon emission in the visible spectral range from InP quantum dots embedded in a resonant cavity LED device structure. The electroluminescence from a single QD can be observed up to 120 K. Our devices can also be operated using pulsed electrical excitation. The successful injection of carriers is verified by time-correlated photon counting experiments and the pulsed signature in second-order autocorrelation measurements.
