FIG. 1.

(a) Schematic diagram of the neutral QD exciton states. The fine-structure splitting is denoted by . and denote the initial photon state and exciton energy, respectively. (b) Schematic diagram of the excitation of charged dots with a spin up/down electron by a -polarized laser pulse. Absorption is only possible in the dot with the spin up resident electron.

FIG. 2.

Pump-probe transients measured in co- and cross-circular configurations (black and grey, respectively) for (a), (b) , (c) , (d) , and (e) .

Image of FIG. 3.
FIG. 3.

(a) Evolution of the polarization degree for and as deduced from the data in Fig. 2. (b) Probability of QD single and multiple charging as a function of the injection current and current density. The inset in Fig. 3(a) shows the dependences of and injection current on the applied forward bias .
