Abstract:

For the soliton solution of coupled nonlinear Schrodinger equations, their collision behavior in the nonlinear left-handed materials is important for the propagation research on this kind of solitons. In this paper, we employ the Split-Step Fourier Method (SSFM) to simulate the collision process of two solitons with the same envelope. Simulation shows that the two solitons with the same envelope can keep their properties unchanged in the collision, such as their shape and velocity. By neglecting the loss, after the collision, the two solitons continue to propagate without loss of their own initial state and properties in the nonlinear left-handed materials. These results provide the knowledge of the propagation and collision of solitions which is the soliton solution of the coupled nonlinear Schrdinger equations in the nonlinear left-handed materials.

Key words: metamaterials, solitons, collision, nonlinear, left-handed materials
