In this article, a finite difference scheme for coupled nonlinear Schrodinger equations is studied. The existence of the difference solution is proved by Brouwer fixed point theorem. With the aid of the fact that the difference solution satisfies two conservation laws, the finite difference solution is proved to be bounded in the discrete L-infinity norm. Then, the difference solution is shown to be unique and second order convergent in the discrete L-infinity norm. Finally, a convergent iterative algorithm is presented. (C) 2010 Elsevier Ltd.
