Fiber Bragg Grating (FBG) is used as modeling and simulation for temperature sensor

摘要

This paper deals with mathematical modeling, design and application of Fiber Bragg Gratingas temperature sensor .In this paper we used the MATLAB and filter characteristics simulation softwareas a tool for simulation results. The fabrication of Fiber Bragg Grating, their characteristics andfundamental properties are described. The reflectivity of FBG is described using simulation results.This paper also presents the simulation results of FBG as temperature and gas sensor. From theplotting analysis it can be concluded that for reduce the width of reflection spectrum we can take longgrating
