| 摘 要： | 研究了非理想光源对孤子通信系统的影响,用变分方法分析初始波形失配的影响,用数值方法分析了频率啁啾的影响,并用逆散射微扰方法分析了光源噪声的影响.结果表明,初始波形的失配引起脉冲脉宽的周期性变化,初始频率啁啾的存在也会引起脉宽的涨落,而光源噪声则引起脉冲到达时间产生抖动. |
| 关 键 词： | 光孤子 波形失配 频率啁啾 光源噪声 |

| Abstract: | In this paper,the influence of non ideal optical source on solition communication system is studied.The effect of initial waveform mismatch is analyzed using variational approach.The effect of initial frequency chirping is analyzed with numerical method.And the effect of optical source noise is investigated with perturbed inverse scattering method.The results indicate that the mismatch of initial waveform induces periodic variation of pulse width,the existence of initial frequency chirping results in the fluctuation of pulse width,and optical source noise leads to pulse arrival time jitter. |
| Keywords: | Optical solition Waveform mismatch Frequency chirping Optical source noise |
