Quantum optomechanical system serves as an interface for coupling between photons and phonons via radiation pressure. We theoretically investigate the optical response of a hybrid optomechanical system that contains a single undoped semiconductor quantum well inside a cavity as well as a thin dielectric movable membrane in the middle, quadratically coupled to the cavity photons. We find that in the presence of both quadratic optomechanical coupling and exciton-cavity field coupling, two additional absorption dips appear in the output field spectrum of the probe field as compared to a standard quadratic optomechanical system which gives only two-phonon optomechanical induced transparency and optomechanical induced absorption phenomena with probe field detuning. This is due to the formation of the dressed state mediated by the single-photon state and the exciton mode. Furthermore, we have shown that the optical transmission of the probe field at these two absorption dips can be controlled by a number of parameters present in the system like exciton-cavity field coupling strength, decay rate of exciton as well as the mean number of thermal phonons- in the environment. We also explore the possibility of slow light in this absorption regime due to exciton-photon coupling. Our study shall provide a method to control the propagation of light in quadratic hybrid optomechanical system containing semiconductor nanostructures.
