Dynamic Behavior of Optical Soliton Interactions in Optical Communication Systems

In optical systems,it is necessary to investigate the propagation of optical solitons in optical fiber systems for fiber-optic communications.By means of the bilinear method,we obtain the two-soliton solution of the variable coefficient higher-order coupled nonlinear Schrodinger equation.According to the obtained two-soliton solution,a novel two-soliton interaction structure of the system is constructed,and their interactions are studied.Two optical solitons occur with elastic interaction under certain conditions,and their amplitudes,shapes and velocities remain unchanged before and after the action.In addition to the elastic interaction,splitting action and polymerization also occur.The present study on the dynamic behavior of interaction of optical solitons may be valuable for research and applications in optical communication and other fields.
