Radiative emission dynamics of quantum dots in a single cavity micropillar
The light emission of self-assembled $(\mathrm{In},\mathrm{Ga})\mathrm{As}∕\mathrm{Ga}\mathrm{As}$ 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 …
