In order to achieve all-optical diode function, a 1-D photonic crystal nonlinear microcavity was designed with metal films in different thickness coated on both sides of the photonic crystal. Transmission properties of the microcavity were studied with the nonlinear transfer matrix method. The results show that structure coupling both the nonsymmetric optical Tamm states and nonlinear microcavity shows bistable states with all-optical diode feature, and that the position of hysteresis loop is related with incident direction. The diode performance is dependent on the thickness of nonlinear microcavity and the ratio of thickness of the metal films on both sides. The design provides a reference for the optimization design of all-optical diodes.
