A novel singlemode-multimode-thinned-singlemode (SMTS) fiber structure based Mach-Zehnder interferometer (MZI) is
proposed for measurements of liquid level and refractive index (RI). We observe that the liquid RI information can be
provided from the sensitivity of the interference peak shifts. Furthermore, by measuring the certain wavelength shift, the
liquid level can be measured accordingly. A 9.00 mm-long thinned fiber with core/cladding diameters of around 4.5/80 μm
is used. The wavelength of 1538.7228 nm exhibits a water level sensitivity of -175.8 pm/mm, and refractive index
sensitivity of -1868.42 (pm/mm) / RIU, respectively. Moreover, the fabrication process is very simple and cost effective.
