FIG. 1.

PL spectra of an individual GaAs quantum dot. Emission from the neutral exciton with fine structure splitting and the positively charged exciton . Full squares (open circles) correspond to linearly polarized emission along [110] . Solid lines indicate fits obtained with Lorentzian line shapes. The selection rules for optical transition between conduction electrons and valence holes are shown in the inset.

(a) Polar plot of the charged exciton emission intensity for different positions of the linear polarization analyzer relative to [110] crystallographic direction. (b) Neutral excitons (gray) and (red). The solid (black) lines indicate the theoretical calculation. by fitting with Eqs. (1)–(3) we obtain .
