A novel design for all-optical NAND/NOR/XOR gates based on nonlinear directional coupler
In this paper a novel all-optical logic NAND, NOR and XOR gate based on nonlinear directional coupler theory is demonstrated. We use the identical structure which contains three waveguides, for designing these gates; the only difference however, is the power of inputs light beam. In other words, while a beam with 4 W/μm in power considered as logical one, the output is NAND gate and if a beam w...

متن کاملRealization of Xor and Xnor Gates Using Qca Basic Gates
Quantum dot cellular automata is an emerging nanoelectronic computational architecture which has the potential of faster speed, smaller size and minimum power consumption compared to transistor-based technology. In QCA, binary information are encoded as electronic charge configuration of a cell. Fundamental unit in building of QCA circuit is a QCA cell. A QCA cell is an elementary building bloc...
