A Variational Study on the Propagation Properties of Optical Bright-Soliton-Like Pulses in Optical Fibers
The influence of perturbation on the propagation properties of optical bright-soliton-like pulses is investigated in optical fibers by means of variational method, and the evolution equations for the parameters of the optical bright-soliton-like pulse is derived. These equations are the unity of the evolution equations for the parameters of the optical bright-soliton-like pulse among monomode optical fibers, the fiber with slowly decreasing dispersion or dispersion-managed optical fibers. By these equations, the perturbation of linear high-order dispersion in the fiber is calculated. The results show that linear high-order dispersion affects the position and the phase, doesn't affects the amplitude ,the width and the chirp of the bright-soliton-like pulse. The slowly decreasing dispersion affects all of the parameters of the optical bright-soliton-like pulse.
