摘要：
In this paper, a coupled nonlinear Schrodinger (CNLS) equation, which can describe evolution of localized waves in a two-mode nonlinear fiber, is under investigation. By using the Darboux-dressing transformation, the new localized wave solutions of the equation are well constructed with a detailed derivation. These solutions reveal rogue waves on a soliton background. Moreover, the main characteristics of the solutions are discussed with some graphics. Our results would be of much importance in predicting and enriching rogue wave phenomena in nonlinear wave fields.
