  • 摘要:Optical fiber plays significant roles in optical communications, optoelectronics, and sensors. The FBGsensors exceed other conventional electric sensors in many aspects, for instance, immunity to electromagneticinterference, light weight, compact size, stability, flexibility, high temperature tolerance, and resistant to harshenvironment. This paper provides the operating principle, implementation of a “strain-free” FBG temperature sensorshead and spectral characterization study. High-resolution detection of the wavelength-shifts induced by temperaturechanges are achieved using optical spectrum analyzer. Both uniform Fiber Bragg Grating (FBG) temperature andMach-Zehnder Interferometric (MZI) temperature sensors based on single mode fibers were implemented andinvestigated due to measurement of the Bragg wavelength shift. It has been shown from the results that the FBG is verysensitive to variations in temperature degrees over a temperature range of (5–70) oC and the sensitivity was (1-6pm/0.1°C), also observed from the results, the relation between the shifted Bragg wavelength and temperature degreeswas linear.
