Recently, it has been demonstrated that photon echoes emitted from ensembles of inhomogeneously-broadened quantum dots can be controlled in several ways by suitably designed light pulses [1,2]. The strong coupling of a single two-level system to the mode of a microcavity results in a complex nonlinear optical dynamics [3]. Here, we present numerical simulations of the coherent dynamics of quantum dots ensembles, described as two-level systems, inside a single-mode microcavity. The coupling to the field mode results in a complex dynamics which is studied numerically as function of the relevant system parameters and for different excitation conditions.
