FIG. 3.

(a) Exchange splitting as a function of the exciton energy ( sample). The dashed line shows the spectral resolution limit of the experimental setup. (b) Exchange energy splitting calculated as a function of exchange energy for circular InAs QD on InP substrate. The dashed line shows the part of the curve lower than the resolution limit of the experimental setup.

Image of FIG. 4.
FIG. 4.

spectra at different power excitation densities: (a) single quantum stick of the nominal sample and (b) single quantum dot of the vicinal sample.

Image of FIG. 5.
FIG. 5.

Biexciton binding energy as a function of the exciton energy ( sample). The dashed line is a guide for the eyes.
