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.

Does the grating work or is it the fiber
An optical fiber grating is a small segment within an optical fiber altered to act as a selective filter for light. This treated area functions like a specialized mirror, reflecting a specific wavelength of light while allowing all other wavelengths to pass through.
