Optical bistability (OB) in a hybrid optomechanical system with quantum dot molecules (QDMs) is investigated theoretically. The OB behavior between the optomechanical cavity photon number and the coupling-laser Rabi frequency can be controlled for different system parameters such as their frequency detuning, the coupling strength, the optical cavity decay rate and the tuning strength in the QDMs. The photon number of the optomechanical cavity vs. frequency detuning has been calculated numerically to explain the OB. It is revealed that the tunneling effect in the QDMs can be used to adjust the OB finely. Such a system may be used in the bistable optical switching and other quantum information technology..
