TEMPERATURE MONITORING SYSTEM USING FIBER BRAGG GRATING FBG

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.

Fiber Bragg grating output

An Optical Fiber Bragg Grating (FBG) is a periodic modulation of the refractive index within the core of an optical fiber. This structure acts as a wavelength-selective reflector, transmitting most wavelengths while reflecting a narrow band centered at the Bragg wavelength (λ B). The fibre Bragg grating can perform many primary functions, such as reflection and filtering for example, in a highly effi ient, low loss manner. They feature low thermal slope with our high-power package and can andle kW-level pump and signal power. Custom desiA variation of the period of the grating inscripted in a fiber optic – induced by mechanical or thermal perturbation – causes a shift of the reflected peak wavelength, due to the related optical path length variation.
