Multimode soliton evolution in GRIN fiber 1

Simulation results of temporal field evolution and spectral evolution of total field, mode 1, and the remaining 14 modes vs. input pulse energy for different propagation distances in graded-index fiber with 50 μm, under the condition of an input Gaussian beam width r_w=2 and center offset r_s = 0.
