Semiconductor quantum dot-a quantum light source of multicolor photons with tunable statistics

Summary form only given. We report on measurements of temporal correlations among multi-color photons emitted from cw optically excited single semiconductor quantum dots (SCQD). We show for the first time, that there is a tunable intensity correlation among photons emitted at the same and at different wavelengths due to the recombination of electron-hole (e-h) pairs from different collaborative quantum states. We show that the temporal correlations among the photons emitted by the SCQD change dramatically with the excitation power.
