| 摘 要： | 用分步傅里叶方法分别对光孤子的传输方程和准光孤子在色散位移光纤中的传输方程进行了数值模拟,模拟结果表明,准光孤子的脉宽比光孤子的窄,在传输中脉冲形状保持不变,更加有利于作通信中的信号载体.

| Abstract: | The transmission equations of soliton, and of quasi-soliton in dispersion management fiber were simulated by the split-step Fourier method. The results show that the pulse width of quasi-soliton is smaller than soliton, and its pulse shape of quasi-soliton can be invariable kept, which makes it be a better candidate for signal carrier in communication. |

| Keywords: | soliton quasi-soliton split-step Fourier numerical simulation |
