摘要：

Using micro-photoluminescence, we demonstrate single-photon emission in the visible (red) spectral range using self-assembled InP quantum dots embedded in a planar microcavity realized by monolithically grown high reflectivity AlGaAs distributed Bragg reflectors. A full width at half maximum of 130 mu eV at 5 K was observed from a single quantum dot coupled to the fundamental cavity resonance. Photon correlation measurements performed under continuous wave excitation show a clear antibunching behavior [g((2))(0)=0.13] as expected for a single-photon emitter. Saturation count rates up to 1.5 MHz (8.1 MHz into the first lens, with an extraction efficiency of 4.1%) were observed. (C) 2008 American Institute of Physics.
