A dual-cavity optomechanical system driven by squeezed light is employed to implement photon blockade (PB) effect based on two different physical mechanisms. In the first mechanism, the weakly squeezed light induces quantum destructive interference between different two-photon excitation pathways, enabling unconventional PB in a single cavity. In the second mechanism, a strong squeezed light is exploited to enhance Kerr nonlinearity induced by the optomechanical coupling, resulting in the simultaneous conventional PB in both cavities. By controlling the intensity of squeezed light and adjusting the frequency of pumping light, the PB effect can be selectively achieved for either a single cavity or dual cavities as required. This scheme provides an effective way for advancement of single-photon sources and the applications of squeezed light in optomechanics.
