“…Consequently, extensive research combines various materials with photonic crystal fiber [ 1 , 2 ], hollow-core fiber (HCF) [ 3 , 4 ], twin-core fiber [ 5 ], and D-shaped fiber [ 6 ] for the fabricated FMZIs. The silica-based fibers combined with the other materials, including liquids [ 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 ], nanoparticles [ 13 , 14 ], and 2D materials (graphene) [ 15 , 16 , 17 , 18 , 19 ], would generate much higher sensitivity to external parameters than that of the intrinsic silica fibers. Various configurations for the FMZIs have been proposed in the literature and have been demonstrated their effectiveness [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ].…”

“…Given the high modulation of RIs in the liquids, combining optical fiber has a broad range of applications. The application of fiber-optic sensors combined with liquids entails changing the effective RI of the external surroundings [ 8 ], cladding modes [ 6 , 7 , 9 ], or core mode [ 4 , 12 ] for the FMZIs. In a section on changing the external surroundings of the fiber, the study of Zhu et al reported an FMZI based on tapered hollow optical fiber.…”

We proposed a novel sensor based on an ultracompact leaky-guided liquid core fiber Mach–Zehnder interferometer (LLCFMZI) for high modulation of an interference spectrum. The sensor structure is based on a micro-sized hollow-core fiber (HCF) splicing a tilt end face single-mode fiber (SMF) to create a miniature oblique gap for the effective access of different liquids. The liquid core with a relatively lower refractive index (RI) than the cladding can achieve a leaky-mode optical waveguide (LMOW) mechanism, and its volume is only approximately 7.85 pL. In addition, the utilized micro-length HCF can reduce the energy loss of core in the LMOW to obtain an acceptable extinction ratio (>30 dB) with high temperature (T) sensitivity in the interference spectra. Experimental results show that the interference spectra can be highly modulated within the wide measurement range of 1250–1650 nm with a steadily linear response for thermal effect. The measured temperature sensitivities (T-sensitivities) of various liquids of DI water, ethanol, and Cargille-liquid (nD = 1.305) are 0.8869, 4.4754, and 4.8229 nm/°C, and the corresponding measured thermal optics coefficient (TOC) are −4.16 × 10−5, −2.11 × 10−4, and −3.6 × 10−4 °C−1, respectively. Measurement results demonstrate that the used liquids with a higher TOC can obtain better T-sensitivity modulation. The highest experimental sensitivity of the liquid-core filled with Cargille-liquid (nD = 1.40) is up to +13.87 nm/°C with a corresponding TOC of −4.07 × 10−4 °C−1. Furthermore, the experimental and theoretical values are in good agreement according to FSR the measuring scheme that investigates the effectiveness of the proposed LLCFMZI.

In this paper, we designed a high sensitivity temperature sensor based on Mach-Zehnder interferometer (MZI) and verified experimentally. MZI is a splicing structure of "SMF ̶ MMF ̶ quartz capillary ̶ MMF ̶ SMF". A micro-channel was processed by femtosecond laser pulse on the capillary wall of MZI, and then dimethyl silicone oil (DSO) was injected into the capillary by immersion method. When filled with DSO, the micro-channel is sealed with epoxy glue to form MZI temperature sensor. When the ambient temperatures vary, because the thermo-optic effect of DSO in the capillary of MZI is high, and causing the optical path difference (OPD) in MZI changes, making the wavelength shifts of the transmission spectrum of MZI. Therefore, the high sensitivity of temperature is obtained by demodulating the wavelength shift of the transmission spectrum of MZI. The experimental results show that the temperature sensitivity of MZI filled with DSO is 7.4212 nm/°C in the range of 30 °C ~ 50 °C, which is ~309 times as high as that MZI without DSO (0.024 nm/°C). In addition, the sensor also has the advantages of good repeatability and stability, simple fabrication, good robustness and low cost.
