Abstract

We have studied coherence dynamics of excitons in symmetric coupled-quantum well systems by four- wave mixing spectroscopy. We report that the coherence decay of excitons in the coupled quantum wells shows the quantum beats and different dependence on excitation power from that in a reference multiple quantum well.
