摘要
利用传输矩阵法分析了磁光效应和光栅折射率初始相位对磁光光纤布拉格光栅(MFBG)-法布里珀罗(FP)光谱特性的影响。通过调节外加磁场的大小及方向,能实现MFBG-FP的可调滤波特性,并能控制甚至抵消光栅折射率初始相位差引起的透射峰平移。对于高光栅反射率的MFBG-FP,透射峰位置和波长间隔可由其有效腔长以及等效磁光耦合系数来解析表达。MFBG-FP的磁可调能力会随着FP腔与MFBG的磁光耦合系数比的增加而增强,磁光耦合系数比大于1的MFBG-FP结构的磁可调特性优于相应的MFBG结构。
Abstract
The transmission characteristics of magneto-optic fiber Bragg grating(MFBG)-based Fabry-Perot(FP) structures dependent on the magneto-optical effect and the initial phase of effective refractive index distribution of gratings are analyzed by the transfer matrix method. By adjusting the applied magnetic field, the function of tunable filtering for MFBG-FP structures is implemented and the magnetic control of transmission peaks is also useful for eliminating the influence of the initial index phase difference. For the case of high reflectivity of gratings, the position and wavelength spacing of transmission peaks can be analytically expressed by the effective cavity length and the effective magneto-optic coupling coefficient. The magnetic tunability of MFBG-FP is enhanced with the increase of the ratio of FP cavity to MFBG magneto-optic coupling coefficients. When the ratio is more than 1, the MFBG-FP has an advantage over the corresponding MFBG in magnetic tuning.
