Abstract
The experimental observation of biexcitons in microcavities has been addressed recently. A well-resolved polariton-biexciton transition was observed in a high-quality GaAs single quantum well (QW) /spl lambda/-microcavity of 25 nm well width using a pump-probe experiment. In this microcavity the heavy-hole (HH) vacuum Rabi splitting is 3.6 meV, more than three times larger than the biexciton binding energy in the bare QW (1.1 meV). Due to the narrow linewidth of the polariton resonances, a well-resolved pump-induced optical absorption associated with biexcitons was observed. In this work we investigate the coherent properties of the biexciton in the same structure using a two-beam four-wave mixing (FWM) experiment at 10 K.
