• Photonic crystal
• NAND gate
• Band gap

In this paper we proposed a new design for all optical NAND gate. By combining nonlinear Kerr effect with photonic crystal ring resonators first we designed AND and NOT gates, then by cascading these two structures we implemented a AND -NOT structure which operates as a NAND gate. The switching power threshold obtained for this structure equal to 1 kW/4/mu,m(2). 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 lambda=1550 nm.
