Abstract

We report the selective generation of quantum beats of weakly confined excitons in GaAs thin films. The oscillatory structure is observed in the degenerate four-wave-mixing (DFWM) signals, and the frequency varies with excitation energy. Comparing with the DFWM spectrum, we concluded that the origin of the oscillation is the quantum beat of the weakly confined excitons. Our results indicate the frequency selectivity of the excitonic quantum beats.
