| 摘 要： | 为了分析椭圆双折射对偏振模色散的影响,将模型中的偏振模色散(PMD)矢量及极化相关损耗(PDL)矢量设定为椭圆偏振矢量,应用保偏光纤(PMF)级联模型和蒙特卡罗仿真方法,研究在PDL影响下的PMD统计特性。研究表明,PMD和PDL矢量的椭圆偏振程度对PMD的统计分布和均值大小均会有影响;在椭圆偏振和PDL的联合影响下,PMD的统计分布为Maxwell和Gaussian分布的合分布。研究结果对偏振模色散的测试、补偿和系统设计均具有参考价值。

| Abstract: | In order to study uhe influence of elliptical birefringence on the polarization mode dispersion(PMD),the statistics of PMD with polarization dependent loss(PDL) is studied by using the polarization maintaining fiber(PMF) waveplate model and Monte Carlo simulations based on the elliptical birefringence.It is found that the elliptical birefringenceaffetcts the statistical distribution and mean values of PMD and the statistical distribution of PMD is the combination of Maxwell and Gaussian distribution.The obtained result is favor of the testing,compensation and system design of PMD. |
