摘要： The unconventional photon blockade with weak chi ((2)) nonlinearity in a system consists of two single-mode cavities driving by two external fields is studied in this paper. The photon statistical properties, described by the second-order correlation function, are discussed, and the exact optimal conditions for strong photon anti-bunching is analytically derived. The optimal frequency detuning and nonlinear interaction strength for the strong photon anti-bunching are also obtained, which are in good agreement with numerical simulations. We find that the unconventional photon blockade effect can be controlled by tuning the relative phase between two complex driving fields when the two cavity modes are driven simultaneously. Our results provide a promising scheme for the coherent manipulation of photon blockade through tuning the relative phase between the two driving fields, which makes the experimental realization more flexible.
