An all–optical soliton method for calculating the FFT (Fast Fourier Transform) algorithm is presented. The method comes as an extension of the calculation methods (Soliton Gates) as they become possible in the Cubic Nonlinear Schr?dinger Equation (3NLSE) domain, and provides a further proof of the computational abilities of the scheme. The method involves collisions entirely between first order solitons in optical fibers whose propagation evolution is described by the 3NLSE.
