Abstract

We report the realization of the first electrically-driven single photon source. The device is based on a GaAs p-i-n diode containing self-assembled InAs quantum dots embedded within the i-region. Time resolved electroluminescence from the device yields information on the radiative lifetimes of the single quantum dots involved. Applying a continuous current a dip is measured in the second-order correlation function at zero time delay indicating that the luminescence is antibunched. Under pulsed excitation by subnanosecond voltage pulses, strong suppression of multi-photon pulses is achieved with respect to a laser of the same average intensity. The results suggest that conventional semiconductor technology can be used to mass-produce a single photon source for applications in quantum information technology.
