Investigation on nonautonomous soliton management in generalized external potentials via dispersion and nonlinearity

摘要: We investigate the controllable behavior of nonautonomous soliton in external potentials with variable dispersion and nonlinearity management functions, which describes propagation optical pulses an inhomogeneous fiber system. derive Lax pair a spectral parameter exact multi-soliton solution is generated via Darboux transformation. Based on these solutions, several novel solitons are constructed by selecting appropriate functions main evolution features waves shown some interesting figures computer simulation. As few examples, breathers periodic potential, compression exponentially decreasing interaction boomerang discussed. The presented results have applications study birefringence-managed switching architecture. These potentially useful communications long-haul telecommunication networks.
