Asymmetric W-shaped and M-shaped soliton pulse generated from a weak modulation in an exponential dispersion decreasing fiber Project supported by the National Natural Science Foundation of China (Grant No. 11475135), the Fund from Shaanxi Province Science Association of Colleges and Universities (Grant No. 20160216), and Guangxi Provincial Education Department Research Project, China (Grant No. 2017KY0776). |
(color online) The numerical simulation of the dynamics evolution process from an initial data given by the exact solution at ξ = 375 m (a) for |φ1|2 and (b) for |φ2|2. The numerical simulation corresponding to panels (a) and (b) with small noise. The initial excitation condition is given by the exact solution at ξ = 375 m by multiplying a factor (1+0.01 Random[−1, 1]). The parameters are the same as those in Fig. |
