In the present paper, an all-optical 3-Input NOR gate based on photonic crystals is proposed. In designing this gate, three resonant rings have been used. By employing high intensity optical power into the device based on Kerr effect, the refractive index of the rods has been varied and the coupling of light into output has been controlled. The consistency of simulation results with the logical table of NOR gate confirms the suitable functionality of the device.fatcat:iakm5qqajbh5hdiybbvsr4ncdm
