Dynamical equations for excitonic nonlinearities in MQW structures
Gian Paolo Bava, Pierluigi Debernardi, Luigi A. Lugiato
A model is presented for the dynamical evolution of optical bistable devices based on Multiple Quantum Well structures, in which the electric field is near resonance with an excitonic line, and the parameters which appear in the equations are discussed. For room ternperature operation, examples of steady state response curves are presented. In conditions of adiabatic elimination of the exciton density and within the assumption of small carrier density, it is shown that the set of equations is equivalent to the well known model for optical bistability in two level systems.
