| Abstract: | Cryogenic temperature sensing has been demonstrated using FBGs with polymer coating of various thicknesses and the experimental results have been presented in this paper. Teflon coating applied on Fiber Bragg Gratings which are inscribed in silica fiber (TFBG) with coating thicknesses of 20 and 40 micrometers have been used in the present investigation. The Bragg wavelength was measured in the temperature range from -196°C to 800°C in the case of regular FBGs and TFBGs. TFBGs were found having better linearity and sensitivity compared with the response of regular uncoated FBGs. |
