In this letter, we demonstrate the enhancement of the Rayleigh back-scattering signal in germanium-doped-core silica fibers, using high resolution Rayleigh fiber sensor. Experiments are performed to estimate the thermo-optic coefficients <inline-formula> <tex-math notation="LaTeX">\text{C}_{\mathrm {T}} </tex-math></inline-formula> for different germanium dioxide (GeO 2 ) concentrations. It was demonstrated that, the thermo-optic coefficients increase with the (GeO 2 ) doped concentrations.
