Abstract

The observation of biexcitonic contributions to time-resolved pump-probe measurements of a 25 nm multiple quantum well are reported. Results from wavelength and polarization dependent studies of the differential transmission in the vicinity of the heavy hole exciton transition demonstrate the strong influence of the biexciton state on the nonlinear response. Intensity dependent measurements are consistent with biexciton formation. The previously predicted angle dependence of the beating between light and heavy hole excitons is also observed.
