摘    要:研究了单模光纤布拉格光栅的偏振相关损耗(PDL)特性.运用耦合模理论和琼斯(Jones)矩阵提出了反射光的有效偏振相关损耗(PDLeff),并模拟r其随光栅参数和双折射量的变化性质.光栅反射光的偏振相关损耗在反射谱的带边处明显地表现出来,特别是带边比较陡峭时.结果表明,光栅的有效偏振相关损耗明显地依赖于光栅的结构参数和...

关 键 词:光栅  偏振相关损耗  耦合模理论  琼斯矩阵  双折射

Abstract:Wavelength dependency of polarization dependent loss(PDL) in reflection in uniform fiber Bragg gratings(FBG) written in single-mode fibers(SMF) is studied deteriledly.Effective PDL(PDLeff) and simulations are carried out using the coupled-mode theory and the Jones matrix.The evolution with wavelength of PDLeff as a function of the grating parameters and the birefringence value is analyzed.The PDLeff appears clearly on the band edges of the reflection spectrum,especially with the steep sides.Numerical result...
Keywords:grating  polarization-dependent loss  coupled-mode theory  Jones matrix  birefringence
