Abstract
We resolve spatially, spectroscopically and temporally the photoluminescenc e emission from single self-assembled In(Ga)As/GaAs quantum dots. The rich photoluminescence spectrum and its evolution with time after pulse excitati on and with the density of excitation is experimentally measured and analyz ed using a theoretical multiexciton model. From the quantitative agreement between the measured and calculated spectra, the radiative lifetime of a si ngle quantum dot exciton is unambiguously determined.
