Abstract
Beats in the transient four-wave-mixing signal from strongly inhomogen eously broadened semiconductor quantum wells are observed. Based on th eir phase and polarization properties, the beats are assigned to biexc itons in the mesoscopically disordered material. With increasing excit ation intensity a halving of the beat period is observed and is accura tely reproduced by calculations including fifth-order contributions.
