Radiative lifetime of an exciton in a GaAs quantum well (QW) is controlled by high-density excitons, which restrict the exciton coherence through scattering. In order to circumvent the phase space ΓΏlling e ect of high-density excitons, we have prepared a QW structure in such a way that a reservoir f
