“…The sensitivities of peak A and peak B are obtained by linear fitting, which are 5.91±0.01×10 −5 and 6.55±0.01×10 −4 nm/µε, respectively. The strain sensitivity of peak A decreases one order of magnitude compared with that of the other MZI sensors, which are 0.31 [24] and -0.72 pm/µε [25] respectively.…”

This study proposes a new hybrid Mach-Zehnder interferometric (MZI) sensor based on two core-offset attenuators and an abrupt taper in a single-mode fiber fabricated by a fiber-taper machine and electric arc discharge. When the distance between the two core-offset attenuators is stretched to 4500 µm, significant interference signals are detected with a prominent attenuation peak of ∼28 dB. The proposed MZI can be used to measure temperature due to its low refractive index (RI) and strain cross-sensitivity. The temperature sensitivity is 34.95±0.04 and 106.70±0.04 pm/ • C in the temperature ranges of 14−250 and 250−1000 • C, respectively.

“…Compare to others based on special fiber which also have the characteristics of temperature sensitive and external RI insensitive [18], it shows better linearity and lower external RI response characteristics, so higher-accuracy measurement for solutions' temperature can be realized by utilizing it. Moreover it possesses more less transmission dips which is more convenient to demodulate.…”

A refractive index (RI) insensitive temperature sensor based on specialty triple-clad fiber (STCF) is proposed. Based on coupling mode theory, the STCF can be equivalent to a rod waveguide and two tube waveguides. Then the cladding mode resonance characteristic of STCF is analyzed by calculating different mode dispersion curves, which indicates that it works only on the mode resonance from core to the fluorine-doped silica cladding, and finally a resonance wavelength can be obtained. Two straightforward experiments are performed to prove its sensing properties. Experimental results show that it has sensitivities of 72.17 pm/°C at temperature range from 35°C~95°C with characteristics of insensitive to external RI in the range from 1.3450 to 1.4607. Thus, this proposed sensor can be used for solution temperature monitoring in real time.
