    • Usually the semiconductor Bloch equations must be evaluated beyond the Hartree-Fock limit in the strong nonlinear optical regime, e.g., by taking into account electron-electron scattering in second order Born approximation (Refs. 27-29). These terms usually yield dephasing of the electronic coherence. However, in our case the dynamics are determined by the collective radiative damping, which for many QWs and moderate excitation dominates over the electron-electron correlations.

    • note
    • One signature of our model is that for excitation above the gap, the normalized reflected intensities are slightly greater during the buildup period of the pump pulse than without pulse. This results from a short period of gain during the onset of the pulse. The oscillations in the reflectivity visible at later times are due to beating between the insufficiently numerically resolved continuum states and are purely artificial.
