Abstract
In this paper a novel alloptical logic AND OR and XOR gates based on nonlinear directional coupler theory is demonstrated We use two waveguides for designing and obtaining both AND/OR gates simultaneously These waveguides have similar properties in material and length which applied for the structure of OR/AND and XOR gates The operation of these structures is simulated by use of Rsoft’s BeamPROP simulator Our results show that by using incomplete coupling desired output signal power will be achieved so this gate can be cascaded with other gates in the next stage Also the halfadder function will be obtained with designed all optical logic AND and XOR gates
