Analysis of Edge Characteristics of Grating and Cavity of Fiber Grating-Based Fabry-Pérot Cavity
The initial phase of the two fiber Bragg gratings used in FabryPérot cavity was considered and the reflectivity and transmissivity expressions of fiber grating-based FabryPérot cavity at any FBG’s initial phase were derivated by coupledwave equation. The phase factors in the expression include cavity length modulated by propagation constant, phase mutation of the fiber Bragg grating, initial phase of the two fiber Bragg gratings and fiber grating length modulated by space frequency of the fiber Bragg grating. The influence of the latter two factors on reflection spectrum was analyzed, and a method to regard a fiber grating-based Fabrypérot cavity as ideal FabryPérot cavity was presented.
