摘要
高双折射非线性啁啾光纤光栅(Hi-Fi-NLCFBG)作为一种新型光学器件,在偏振模散(PMD)补偿领域里有着广泛的应用前景。本文首先分析了Hi-Fi-NLCFBG补偿PMD的原理,然后数值分析了Hi-Fi-NLCFBG的光谱特性、时延特性以及温度和应力特性。最后根据分析结果,针对提高Hi-Fi-NLCFBG偏振模散补偿器的稳定性的问题提出了改进意见。
High - birefringence and non-linearly chirped fibre grating( Hi-Fi-NLCFBG) ,as a kind of new-type optics device, is widely used in the field of the compensator to polarization mode dispersion ( PMD). This artical analysed Hi-Fi-NLCFBG principle at first, then numerically analysed the spectrum characteristic of Hi-Fi-NLCFBG, Characteristic, temperature and stress characteristic that prolongs. At last ,according to the analysis result, to resolve the problem of stabilities of the Hi-Fi-NLCFBG compensation machine , some suggestions are proposed .
