The light emission of self-assembled (In,Ga)As∕GaAs quantum dots embedded in single GaAs-based micropillars has been studied by time-resolved photoluminescence spectroscopy. The altered spontaneous emission is found to be accompanied by a nonexponential decay of the photoluminescence where the decay rate strongly depends on the excitation intensity. A microscopic theory of the quantum dot photon emission is used to explain both the nonexponential decay and its intensity dependence. Also the transition from spontaneous to stimulated emission is studied.
