Abstract
Maxwell equations for light incident on a quantum well at the exciton resonance frequency have been solved taking into account the inhomogen eous broadening of the exciton resonance. Inhomogeneous and homogeneou s mechanisms of broadening can be easily distinguished in time-resolve d reflection or transmission spectra where the inhomogeneous broadenin g causes Gaussian-like decay of the signal and oscillations. Experimen tally predicted nonmonotonic time-resolved signal in transmission has been detected in a system of five GaAs/AlGaAs quantum wells.
