FIG. 1.

Size dependence of the fine exciton states near the band edge state (a), and the corresponding linear absorption spectrum for a CdSe QD with a radius of 3 nm (b). The dotted line represents the laser spectrum.

FIG. 2.

Real (a) and imaginary (b) parts of the complex refractive index spectrum of the bright exciton states (, , and ) in a CdSe QD for a given injected pulse area.

FIG. 3.

(a) The real/imaginary refractive index change for the intensity. (b) Normalized absorption change for the individual bright exciton states and spectral integration for all the bright exciton states for the injected pulse area are compared with the absorption change observed in the cocircularly polarized degenerate pump-probe experiment. The inset shows the corresponding state occupancy for an injected pulse area.
