| 摘 要： | 利用琼斯传输矩阵法研究了二阶偏振模色散的统计特性。对数值模拟中出现的偏振模色散随步长变化的问题做了相应的修正 ,利用修正后的模型得到了偏振模色散矢量的频率相关特性 ;模拟了偏振模色散值为 2 5ps时二阶偏振模色散的几率分布 ,所得结果与理论结果能够很好地吻合 ;简单地分析了脉宽为 8ps的高斯脉冲在此条件下的展宽情况 ,指出了高阶补偿的必要性。

| Abstract: | Statistical characteristics of second order polarization mode dispersion (2 nd PMD) are investigated by Jones Transfer Matrix method. The model in which the value of PMD varies with step size in simulation is corrected. Using this corrected model, the frequency correlation function of PMD vector and the probability distribution of 2 nd PMD are obtained when the value of PMD is 25 ps; the results show good agreements with the theoretical prediction. It is necessary to higher order compensation in these conditions by analyzing the pulse broadening of an 8 ps width Gauss pulse briefly. |
