Abstract
We report correlation and cross-correlation continuous wave measurements in II-VI quantum dots grown by molecular beam epitaxy.Combination of spectral selection, saturation measurements and good temporal resolution allowed us to see an antibunching effect on photons from radiative recombination of excitons in a single CdTe/ZnTe quantum dot, as well as cross-correlation within the biexciton (X2)-exciton (X) radiative cascade from the same dot.We discuss the results of our experiments in terms of a model of excitonic multitransitions.
