In this paper,the variable coefficient nonlinear Schrödinger equation with fifth order dispersion in the inhomogeneous optical fiber is investigated to study the impact of fifth order dispersion on attosecond soliton propagation.Based on the Darboux transformation method,soliton solution is constructed with modulated coefficients though Lax pair.We show that the coefficients of GVD and fifth order term are the main keys to control the amplitude,width and phase shift in the model.With the suitable choices of coefficients for the obtained soliton solution,some new types of soliton management through fifth order are presented for the first time.Especially,the influence of fifth order dispersion of the higher order NLS equations with and without modulated coefficients is discussed in detail.We will also highlight the impact of the studies on application in ocean engineering.Obtained results may be potentially useful in the soliton shaping and management in inhomogeneous fibers. 展开更多
