摘要
研究了磁光耦合强度对磁光光纤布喇格光栅中模式转换光反射光谱特性的影响.根据磁光耦合模理论并结合光纤布喇格光栅的传播特性，数值分析了磁光光纤布喇格光栅的磁控特性，得到了3 dB带宽可调的滤波器.采用级联磁光光纤布喇格光栅构造磁控梳状滤波器，实现了40 Gbps归零数据信号的全光时钟提取仿真，分析了时钟信号的抖动性能与磁光耦合参量的关系.
Abstract
The reflection spectra of polarization-mode conversed light in Magnetooptic Fiber Bragg Gratings (MFBGs) dependent on the magnetooptical coupling intensity is investigated.According to the magnetooptic coupled-mode theory combined with the propagation property of fiber Bragg grating,the magnetic control characteristics of the MFBGs are analyzed numerically.The 3 dB bandwidth tunable filter is obtained by adjusting the magnetooptical coupling intensity.The clock extraction of 40 Gbps RZ data signal by utilizing the comb filtering of MFBGs under bias magnetic fields is simulated and the jitter performance of the MFBGs is also analyzed.
