基于法布里-珀罗 (F-P) 谐振器，开发了对啁啾光纤光栅产生的群延迟纹波 (GDR) 的分析。它清楚地显示了 GDR 是如何产生的以及为什么 GDR 的周期沿着啁啾光纤光栅变化。它还可以解释为什么变迹可以抑制 GDR 以及变迹如何影响光栅的啁啾。该理论可用于设计光纤光栅的变迹。
The analysis of the group delay ripple (GDR) generated by chirped fiber gratings is developed based on the Fabry-Perot (F-P) resonator. It shows clearly how the GDR is generated and why the periods of GDR varies along the chirped fiber gratings. It could also explain why apodization could suppress the GDR and how apodization affects the chirp of the grating. The theory could be used to devise the apodization of fiber gratings.
