We study in detail the dynamics of a non-stationary system composed of aQuantum Well confined in an optomechanical cavity. This system is investigatedwith classical and quantized motion of the cavity movable mirror. In both thecases, the cavity frequency is rapidly modulated in time. The resultantperiodically modulated spectra is presented. In particular, we study the effectof two-photon process on the number of intracavity photons. The intensity offluorescent light emitted by excitons in the quantum well is also examined forthese non-stationary systems. It is observed that the initial stage offluorescence spectrum helps in detecting the two-photon process. It is alsonoticed that under strong modulation, two-photon process dominates while underweak modulation, fluorescence dominates. We also analyzed the dynamics of thesystem induced by a periodic modulation of the external pump laser withconstant cavity frequency. This modulation of external laser pump helps inphonon amplification.
