  text: The nonlinear optical response of quantum well excitons excited by optical
    fields is analyzed by numerical solutions of the semiconductor Bloch equations.
    Differential absorption spectra are computed for resonant pumping at the exciton
    resonance and the dependence of the absorption changes on the polarization directions
    of the pump and probe pulses is investigated. Coherent biexcitonic many-body correlations
    are included in our approach up to third-order in the optical fields. Results
    are presented for spatially-direct type-I and spatiallyindirect type-II quantum
    well systems. Due to the spatial inhomogeneity, in type-II structures a finite
    coupling between excitons of opposite spins exists already on the Hartree-Fock
    level and contributes to the absorption changes for the case of opposite circularly
    polarized pump and probe pulses.
