摘要：

Vector-soliton collisions in birefringent nonlinear optical fibers are investigated. The multi-symplectic structure of the coupled nonlinear Schrodinger (CNLS) system was obtained directly from the variational principle. The multi-symplectic structure was discretizated by the multi-symplectic spectral method. Numerical experiment results showed that the multi-symplectic spectral method has the excellent behavior in the long-time numerical calculation. The collisions of the solitary waves are sensitive to the coupled constant beta and the initial velocity V-0. (C) 2008 Elsevier B.V. All rights reserved.
