摘要 分析了光纤光栅 (FBG)偏振模色散 (PMD)产生的原因 :写入光栅用的光敏光纤对紫外光吸收是不均匀的 ,呈指数型吸收。建立了光栅偏振模色散的模型 ,利用建立的模型计算了不同折射率调制的偏振模色散 ,计算的结果与用偏振模色散分析仪测得的结果符合得很好。理论和实验说明了光栅色散对偏振模色散的影响 :光纤光栅的色散增大 ,光栅的偏振模色散也增大。 The polarization mode dispersion (PMD) of fiber Bragg gratings (FBG) is studied. Theoretic analysis and experimental measurement are carried out on FBG. Birefringence of UV-written gratings mainly comes from the asymmetrical absorption of photosensitive fiber, or exponential absorption. Considering the influence of UV-induced fiber birefringence, gratings chromatic dispersion on the PMD of FBG. the model of FBG's PMD is founded. Numerical calculation is in accordance with the experimental measurement. The dispersion of FBG can effect PMD.
