The origin of the polarization-dependent decay of the time-integrated four-wave-mixing is examined by microscopic model calculations, including both energetic disorder and Coulomb correlations. The correlations are treated exactly up to the third-order in the field. Energetic disorder is taken from random distribution functions, over which the optical response is averaged. Analysis show that the disorder-induced dephasing is the result of a destructive interference which requires the treatment of Coulomb correlations in the presence of disorder. The estimated ratio of the decay times for the two configurations is in good agreement with experiments performed on a variety of quantum well samples.
