An all-optical Fredkin gate was proposed and designed. The is a reversible logic gate. For designing the structure we used three different optical nonlinear resonators. wide-bandwidth resonators do not have switching functionality. However, resonator modified to act as an switch in horizontal direction. final designed using four wide-band resonators, twelve sharp ring Simulation results show that maximum rise time for about 5 ps.
