Photon statistics in a weakly driven optomechanical photonic crystal cavity, with Kerr-type nonlinearity, is analyzed both analytically and numerically. Single-photon blockade effect is demonstrated via calculations of the zero-time-delay second-order correlation function g(2)(0). The analytical results obtained by solving the Schrödinger equation are in complete conformity with the results obtained through numerical solution of the quantum master equation. The experimental feasibility with state-of-the-art device parameters is discussed. It is observed that photon blockade could be generated at the telecommunication wavelength, even at lower values of the nonlinear susceptibility parameters and in the weak single-photon optomechanical coupling regime.The system is found to be robust against pure dephasing-induced decoherences.
