80Gb/s All-optical Boolean function XOR has been demonstrated using a dual four wave mixing scheme in two identical highly nonlinear fibers. A numerical model based on nonlinear Schrodinger equation (NLS) in fiber has been employed to simulate the wave mixing process. The NLS equations have been solved using the split-step Fourier method. From the numerical model, system transmission rate is predicted to be as high as 250Gb/s.
