All optical AND gate based on nonlinear photonic crystal ringresonators

In this paper we proposed a new design for all optical AND gate. By combining nonlinear kerr effect with photonic crystal ring resonators first we designed a structure, whose optical behavior can be controlled via input power intensity. The switching power threshold obtained for this structure equal to 1 kW/m2. For designing the proposed optical logic gate we employed two resonant rings with the same structures, both rings at the logic gates were designed such that their resonant wavelength be at =1550 nm. Every proposed logic gate has one bias and two logic input ports.
