摘　　要：The peaks of exciton and biexciton from the single quantum dot(QD)micro-photoluminescence spectra are identified by observing the intensity of those peaks in relation to increasing excitation power.In order to further verify the properties of the exciton and biexciton,we perform auto-and cross correlation measurements.Using the former,we confirm the antibunching property of the signal light emitted from the single QD.Using cross correlation measurement,we verify that the exciton and biexciton emissions originate from the same QD and they are strongly correlated with each other.Lastly,we analyze the behavior of the cross correlation function in both the cases of saturated and unsaturated excitation of the QD.
