Abstract

The leading contribution to the polarization dependent four-wave-mixing signal is shown to result from density induced dephasing processes. Experimental observations are in qualitative agreement with theoretical calculations based on the semiconductor Bloch equations where dephasing due to excitonic screening has been taken into account.
