Abstract

We report the experimental demonstration of single-photon and cascaded photon pair emission in the infrared, originating from a single InAsP quantum dot embedded in a standing InPnanowire. A regular array of nanowires is fabricated by epitaxialgrowth on an electron-beam patterned substrate. Photoluminescence spectra taken on single quantum dots show narrow emission lines. Superconducting single photon detectors, which have a higher sensitivity than avalanche photodiodes in the infrared, enable us to measure auto and cross correlations. Clear antibunching is observed g^(2) 0 = 0.12 and we show a biexciton–exciton cascade, which can be used to create entangled photon pairs.
