Home / Simulation of Fiber Bragg Grating Temperature Variation
In this study, the behavior of FBGs under varying temperatures is modeled using Coupled Mode Theory (CMT), which provides an analytical framework for the coupling of forward and backward propagating modes within a periodic refractive index structure. It should be noted that temperature and strain sensitivities must be considered, when high performance of the optimal sensor is required. In this topic, we demonstrate how to simulate fiber Bragg grating (FBGs) using MODE'. 5, and a periodic variation of 1e-3 in the refractive index of the core of a step-index fiber. The optical properties of FBG and LPG are firstly analyzed and, consequently, the basics of simulation models are provided.
