In recent years, all-optical diodes based on photonic crystal heterostructures have attracted much attention, and their good characteristics of one-way transmission are the long pursued target. In this paper, different optimized designs are proposed by modifying the photonic crystal structure at the heterostructure interface. And the all-optical diodes with high contrast, which have both efficient unidirectional transmission and beam splitting, are realized in wide bandwidths.
