Nondegenerate solitons of 2-coupled mixed derivative nonlinear Schrödinger equations

The nondegenerate vector one-soliton and two-soliton solutions of the 2-coupled mixed derivative nonlinear Schrödinger equation are acquired by the Hirota bilinear method. The amplitude, intensity and velocity of the vector one-soliton are determined by diverse wave numbers. The research of the collision dynamics for nondegenerate vector two-soliton indicates that energy conversion always occurs in such coupled system. This remarkable feature provides the possibility for the design and development of optical communication in the future.
