Summary:
In this paper, we report thermal characteristics of a FBG temperature sensor in germanium(Ge) doped and Ge & Boron(B) co-doped fiber, including peak reflectivity, FWHM line-width, and various refractive index change as well as thermal stability of a FBG temperature sensor. Ge doped FBG temperature sensor has thermally stability better than Ge & B co-doped FBG temperature sensor. Also, both FBG temperature sensor has thermally stability up to about 500°C and 1000 hours.
