The propagation of a single intense laser pulse through a semiconductor microcavity is presented where the pulse is resonant with 1 s exciton. A GaAs/AlAs microcavity structure was considered with two distributed Bragg reflectors. The light propagation in the multilayer system was solved by time-dependent Maxwell's equations. The source term of Maxwell's equations contains the macroscopic quantum well polarization, which is computed using many-body theory. The many-body treatment of carrier and polarization interaction within the second Born approximation scheme provides a consistent description of the nonlinear exciton saturation. This results from the broadening as well as reduction of exciton oscillator strength and band-gap renormalization.
