Simulation Design of Ϝiber Bragg Grating Temperature Sensor Based On Optical Fiber Interferometric Technology

Abstract

Photonic sensors have of high interest in recent years due to their amazing features and properties. In this work, a Fiber Bragg Grating temperature sensor had been designed and simulated. Two different structure were chosen; Mach-Zehnder and Fabry –Perot interferometry sensors. This is achieved utilizing OptiSystem simulation software. A shifting in Bragg wavelength was achieved due to the application of temperature degrees in the range of (10-110) ˚C. Both sensors exhibit good sensitivity and linearity. The sensitives were equal to 15 pm/ ˚C and 10 pm/˚C for FBG temperature sensor based on MZI and FPI techniques respectively.
