Abstract

Single-photon correlation and microphotoluminescence spectroscopy are employed to characterize the emission from disordered InGaAs/AlGaAs quantum wires grown in inverted tetrahedral pyramids. Recombinations of neutral and charged excitons, localized by wire potential fluctuations, are identified. Antibunched photon emission is observed from both excitonic species that are shown to recombine at the same disordered wire site. This demonstrates the use of single-photon correlation spectroscopy for obtaining spatial information on optical processes in nanostructures.
