Abstract
In order to study the effect of high-order dispersion on propagation of optical soliton and soliton couple,based on the split-step Fourier transform method,the optical soliton nonlinear SchrÖdinger equations with and without high-order dispersion effect were numerically calculated.It is found that the soliton pulse shape is correlative with the dispersion order.The oddnumber -order dispersion effect can cause the soliton and the soliton couple to oscillate at a single side with a loss of energy,and the sub pulse can be produced at the oscillating side.While the even-number-order dispersion effect can make the pulse width extended.The effect of the high-order dispersion would be weakened with the increase of the order number.
