Photon correlation spectroscopy of a single quantum dot

Year: 2002

Type: article

Abstract: We report photon correlation measurements that reveal unique signatures of biexciton and charged exciton emissions in a single self-assembled InAs quantum dot. Biexciton emission exhibits both bunching and antibunching under continuous-wave excitation and only antibunching under pulsed excitation. Cross correlation between biexciton and single-exciton emissions reveals highly asymmetric features due to cascaded emission. Under our excitation conditions, no polarization correlations between the exciton and biexciton emissions were observed.
