摘　　要：The manipulation of photons is a key technology for obtaining optical quantum information.In this study,we present a phase-modulated optomechanical system comprising two coupled cavity resonators and illustrate the phase-controlled photon blockade in the system.The coupling phase of the cavities reveals the interference of photons and introduces an unconventional photon-blockade effect.We also study the influence of the energy level fineness on the photon blockade and resonant frequency of the mechanical mode.Numerical simulations demonstrate that photon blockade can occur over a wide range of system parameters.These results have several implications for understanding the role of the state phase in quantum cavity optomechanics and provide a promising method for the realization of optomechanical quantum devices using photon blockade.
