    • Note that, for a QD ensemble under the irradiation of spectrally broadened laser pulses, both spin-up and spin-down electrons will be excited by σ+ or σ-polarized light (just with unequal excitation probabilities which differs from the linearly polarized case), due to heavy-light hole mixing and allowable transitions which involves heavy, light, and split-off hole states as well. However, this only lowers the generated spin polarization but does not change the net spin orientation.
