Abstract

We propose and simulate all-optical simultaneous half-adder, half-subtracter, and OR logic gate at 40 Gbit/s based on the cascaded sum-and difference-frequency generation (SFG+DFG) using only one periodically poled lithium niobate (PPLN) waveguide. The SFG and DFG processes generate the Borrow and Carry outputs, respectively. The Sum/Difference and OR are obtained by properly combining the outputs from PPLN after SFG+DFG. The eye diagrams, pulse width, quality-factor (Q-factor), extinction ratio (ER), and tunability are calculated and discussed,showing impressive operation performance.
