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
