For further understanding optical secure communication, we study chaos synchronization modeled by the nonlinear Schrödinger equation with Kerr law nonlinearity. By Melnikov method, we get the chaos signal which generated from rupturing of homoclinic orbits. By using feedback control technology and Lyapunov stability theory, we obtain the sufficient criteria of of chaos synchronization. Finally, we analysis the effects of all parameters on synchronization. Result shows that faster wave speed, higher perturbation amplitude and larger nonlinear dispersion coefficient can delay the process of synchronization. Meanwhile, larger control coefficient can speed up the process of synchronization.
