Calculated pump-probe signal of a QD embedded in a microcavity for left-polarized pump and right-polarized probe fields. The intensity is normalized by maximum intensity in the absence of the cavity. Dotted lines represent the resonant conditions for exciting the cross-polarized states calculated from Eq. (16).
Calculated as a function of and , where is focused on (a) the upper and (b) lower levels of states.
(a) -dependence and (b) -dependence of as a function of probe-field frequency . The pump-field frequency is tuned to the lower level of the states. The spectrum shown in Fig. 1 is calculated along the condition indicated by horizontal lines. Spectral peaks corresponding to the resonant excitation of the states are indicated by L and U, respectively, and peaks corresponding to the resonant excitation of the cross-polarized states are indicated by T. Strong suppression of the intensity occurs at the conditions indicated by .
-factor dependence of as a function of pump-field frequency . Calculated regions of the -factor are (a) , (b) , and (c) .
