文摘In this paper, we solve numerically the nonlinear Schrodinger equation for a defocusing Kerr media with initial conditions different to the hyperbolic tangent function. We demonstrate that initial conditions with a similar position dependence than the hyperbolic tangent evolve to a hyperbolic tangent function, therefore can be considered as （1＋1）-D spatial solitons. The waveguide induced by these conditions is not single mode; it has the capacity to confine one mode more.
