Light propagation in a finite nonlinear one-dimensional photonic crystal coated with a metal film is theoretically investigated through the nonlinear transfer matrix method and the finite-difference time-domain (FDTD) method. It is found that the layered structure exhibits both pronounced unidirectionality and high transmission. This leads to all-optical diode actions. Compared with other similar studies, the designed structure has some advantages. First, the structure only with seven periods is much simpler than presented similar structures; second, the structure has both high transmittance and large transmission contrast; third, the perfect performance of AOD is robust to the metal loss.
