Abstract
We study the nonlinear dynamical behavior of cavity polaritons in a semiconductor microcavity with a multiple quantum-well structure. It is shown numerically within the framework of the semiclassical model that for a sufficiently strong exciton-photon coupling and a sufficiently large number of wells the energy exchange between the photon mode and electronic oscillators may become chaotic in the strong-coupling regime even in the case of a vacuum cavity field. The image of dynamical chaos is provided by a topographical map that shows the maximum Lyapunov exponent calculated as a function of the system's control parameters.
