| 摘 要： | 研究了线性系统中偏振模色散对均方根脉宽的影响。考虑了光源初始啁啾的作用 ,推导出均方根脉宽的解析表达式 ,分析表明 :二阶偏振模色散对脉冲展宽的作用与群速度色散及啁啾有关 ,一阶偏振模色散的作用则与这两者无关。以啁啾高斯脉冲为例 ,推导出一阶偏振模色散补偿前、后均方根脉宽的解析表达式 ,结果表明 ,适当选择群速度色散和初始啁啾参数 ,可以有效地抑制偏振模色散的展宽效应 ;与主态传输法比较 ,啁啾的存在对后向补偿方法的影响更大 |

| Abstract: | The impacts of polarization mode dispersion (PMD) on the pulse width in linear systems have been investigated. The analytical solutions, including the effects of initial frequency chirp, are derived. The results show that the broadening effects induced by the first order PMD are independent on group velocity dispersion (GVD) and chirp, which are different from the effects induced by the second order PMD. An initially chirped Gaussian pulse is taken as an example. Analytical solutions of rms pulse width are obtained before and after first order PMD compensation. It is shown that the broadening effects will be suppressed effectively by appropriately choosing GVD and chirp parameter; the post transmission compensation method will be less efficient than the PSP transmission method due to chirp. |
