Abstract

A reflection-type refractive index sensor with an edge-rounded end face of a multimode fiber is proposed and fabricated. The fabricated sensor with the designed structure shows a two-mode interference spectrum. The measured and calculated free spectral ranges in the spectra agree well with each other. The fabricated sensor coated with titanium shows sensitivity as high as 311 nm/RIU even with a sensor length less than 1 mm.
