Sensitivity enhancement experimental demonstration using a low cutoff wavelength SMS modified structure coated with a pH sensitive film

•Fiber optic sensors that operate in the visible light spectrum have been developed.•It is possible to increase the sensitivity of these devices by reducing the diameter of the sensible region.•The wavelength shift in the proposed sensors was verified when they were immersed in different refractive...
