We theoretically investigate the transmission profile of the probe field in a quantum well-based optomechanical system with a resonator driven by a time-dependent mechanical driving force. We show that when the probe field is coupled only with exciton mode, it exhibits amplification; however, when coupled with mechanical mode or both simultaneously, it shows attenuation. On account of the tripartite (photon–exciton–phonon) coupling parameters, the amplification and attenuation of the probe field can be suppressed or enhanced. We illustrate that by properly adjusting the amplitude and phase value of the time-dependent mechanical driving force, the amplification and attenuation of the probe field can be increased or decreased. Further, we reported the Fano profiles of the outgoing field, and the propagation of group delay in a region where the transparency dip occurs. Based on experimentally feasible parameters, our theoretical model provides new insights for future polaritonic-based optical transistors.
