6 Fiber Bragg Grating sensor
Cladding Core Broadband light FBG: longitudinal periodic variation of the refractive index in the optical fiber core DlB (T, e) lB: Bragg Wavelength neff : effective refractive index of the core Λ: grating period Strain and Temperature sensitive: : photo elastic coefficient : thermo-optic coefficient : thermal expansion coefficient Antonella Chiuchiolo - 4th EuCARD-2 Annual Meeting - Glasgow

7 FBG for Cryogenic FBG temperature sensitivity:
room T < 0.1 pm/K below 50 K Bare FBG no suitable for cryogenic temperature! Bare FBG Coated FBG The thermal response of a bonded or embedded FBG is dominated by the thermal expansion/contraction of the host material [H. Zhang et al.
