1All optical NAND gate based on nonlinear photonic crystal ring resonator显示文摘In this paper we proposed a new design for all optical NAND gate.By combining nonlinear Kerr effect with photonic crystal ring resonators,we designed an all optical NAND gate.A typical NAND gate is a logic device with one bias and two logic input and one output ports.It has four different combinations for its logic input ports.The output port of the NAND gate is OFF,when both logic ports are ON,otherwise the output port will be ON.The switching power threshold obtained for this structure equals to 1.5 kW/lm2.For designing the proposed optical logic gate we employed one resonant ring whose resonant wavelength is at 1554 nm.The functionality of the proposed NAND gate depends on the operation of this resonant ring.When the power intensity of optical waves is less than the switching threshold the ring will couple optical waves into drop waveguide otherwise the optical waves will propagate on the bus waveguide.Somaye Serajmohammadi Hassan Absalan 2016Information Processing in Agriculture2016,3,2:1
