Optical logics will play a crucial role in the next generation all optical data processing networks. Therefore an all optical majority gate will be designed by using nonlinear photonic crystal ring resonators. For realizing the proposed structure we need three nonlinear resonant rings. In order to make nonlinear resonant rings, we used chalcogenide glass as the dielectric material for the dielectric rods. The output port of the proposed structure will be active only when two or three logic input ports are active. The rise and fall time values of the proposed structure are about 2 and 1 ps, respectively. The total footprint of the proposed structure is about 1287 μm2.
