fluorescence of quantum dots with antibunched counts were too weak to be recorded. We believe the stronger Auger rate of 70 ps is the preferred route for the multiple excitons, ultimately emission coming only from the single exciton. Characterizing single core-shell QDs with time-resolved confocal. As a result g 2(0) can be reduced up to several orders of magnitude with proper system parameters, compared with the one-mode driving system. The strong antibunching reveals that the probability of radiative recombination with more than one exciton is very low. and Bawendi MG (1997) (CdSe)ZnS core-shell quantum dots: Synthesis and characterization of. The antibunching character can be optimized by regulating the ratio between driving strengths of two cavity modes to achieve optimal combination of superbunched and coherent light. Atkins PW and Friedman RS (1997) Molecular Quantum Mechanics. Coincident photon histogram measurements of fluorescence antibunching via confocal microscopy correlated with atomic force microscopy were carried out on (i) individual CdSe/ZnS core/shell quantum dots (QDs), (ii) several well separated QDs, and (iii) clusters of QDs. The effect of additional cavity mode driving on statistical characteristics of photon emission is presented by evaluating the zero-delay second-order correlation function g 2(0). We study the two-mode coherent driving regime of the coupled system. Arruda,1,2, Romain Bachelard,3 John Weiner,2 Sebastian Slama,4 and Philippe W. Antibunching is a characteristic of light with sub-Poissonian statistics. It is shown in a recent work that the system can generate strongly sub-Poissonian light when one of the cavity modes is driven coherently and resonantly.

We theoretically investigate the photon statistics in a cavity quantum electrodynamics system of a single quantum dot coupled to a bimodal nanocavity.
