Abstract
The interplay of disorder effects and exciton-exciton interactions in the four-wave-mixing process in quantum wells is investigated. Experim ents are performed employing femtosecond and picosecond pulses to have either good temporal or good spectral resolution. It is shown that th e localisation of excitons is of primary importance in the generation of the nonlinear signal. It is shown which states contribute and how t o the FWM process.
