The objective of the work includes in the new design of adiabatic directional full couplers can obtain respectively theory ranges, low noise, large frequency and short couplers. It is surely that the proposed waveguide structure design is more effective than convention weighting for ODC’s.

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...
