In this paper, we present the sensitivity characteristics of core and cladding modes in weakly tilted fibre Bragg grating sensors with different cladding thicknesses. Both experimental and analysis results are presented. The results show that the strain sensitivity of cladding mode resonances in tilted fibre Bragg gratings does not depend on the cladding diameter but on the wavelength separation from the core resonance over the range of the cladding diameters studied.
