| 摘 要： | 运用耦合模理论和传输矩阵分析法推出了反射光的偏振相关损耗,并模拟了在不同双折射值下反射偏振相关损耗随波长变化曲线.随着双折射量的变化,光栅反射光的偏振相关损耗在反射谱的带边处能明显的体现出来,尤其是在带边比较陡峭时.光栅的偏振相关损耗随双折射量的增加迅速增大,随着双折射的变化其PDL的左右峰值呈线性变化,PDL的最大值...

| Abstract: | Used coupling theory and transfer matrix analysis launched the reflected light polarization dependent loss,the different birefringence value reflect the polarization dependent loss curve of the wavelength are simulated.The polarization of the reflected light grating related loss in a reflective spectrum with side is clearly reflected,especially in comparison with steep edge.With birefringence the polarization of the grating related loss is increased rapidly.The birefringence value on the chirp grating polarization dependent loss shows significant influence.The theory analysis and experiment results are matchable each other. |
