在忽略 FBG(光纤 Bragg 光栅)非线性效应的情况下,研究了单模光纤非线性效应对 FBG FP(法布里-珀罗)腔输出特性的影响,导出了连续波及脉冲激光入射时,FBG FP 腔透射率的数学表达式。研究结果表明,连续波入射时,FBG FP 腔呈现双稳态输出特性；脉冲激光入射时,FBG FP 腔的输出呈现衰荡特性,且出现调制不稳定性。
在忽略 FBG(光纖 Bragg 光柵)非線性效應的情況下,研究瞭單模光纖非線性效應對 FBG FP(法佈裏-珀囉)腔輸齣特性的影響,導齣瞭連續波及脈遲激光入射時,FBG FP 腔透射率的數學錶達式。研究結果錶明,連續波入射時,FBG FP 腔呈現雙穩態輸齣特性；脈遲激光入射時,FBG FP 腔的輸齣呈現衰盪特性,且齣現調製不穩定性。

With the nonlinear effects of Fiber Bragg Grating (FBG)ignored,this paper investigates the impacts of the nonlinear effects of single-mode fibers on the output characteristics of FBG FP cavity and derives the mathematical expression for the transmissivity of FBG FP cavity in Continuous Wave (CW)and pulsed laser injection.The results show that the FBG FP cavity exhibits bistable output characteristics in CW injection and ring-down characteristics in pulsed laser injection,and modulation instability emerges.
