| Abstract: | A form of symmetric split-step the solitons propagation. The propagation of Fourier method is carefully discussed. Use Matlab software to simulate ground-state soliton and third-order soliton is simulated. The interactions of two first-order solitons and two second-order solitons are researched. The analysis of how to choose the form of Fourier tansformation and inverse Fourier transformation is made. The results show that this form of symmetric split-step Fourier method can be applied in the simulation of optical solitons propagation. |
