FBG FP腔对连续波与脉冲激光入射的响应
|
摘要
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。
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.
