“…When the light wavelength is far from the resonant cavity, the light will be reflected back by the F-P cavity, confined in the low-refractive-index layer (n1), and propagated forward along its axial direction, which shows a very small transmission loss in the transmission spectrum. In accordance with the reflectivity formula of symmetric parallel flat-plate multibeam interference, the transmission spectrum expression of the AR effect can be obtained as follows [31]: When the external temperature changes, the change in the length and refractive index difference of the FMF will change the optical range difference between the two paths owing to the thermo-optical effect and thermal expansion effect, which in turn will cause a wavelength drift in the transmission spectrum. Therefore, the relationship between wavelength drift and temperature can be described as [30] ∆λ…”

A simple and novel hybrid interferometer based on the antiresonance (AR) effect and Mach–Zehnder interference (MZI), which enables simultaneous measurement of temperature and strain, is proposed and investigated. The sensor is made by cascading a 30 cm section of a few-mode fiber (FMF) and a 3.376 mm hollow-core fiber (HCF) through a single-mode fiber (SMF). The FMF and SMF are fused without misalignment to excite two stable modes, thereby forming a Mach–Zehnder interferometer. Concurrently, the introduction of HCF can effectively excite the AR effect, which is manifested in the transmission spectrum as two different dips at the same time caused by the difference in the two physical mechanisms, showing diverse responses to both external temperature and strain. This difference can be used to construct a cross-coefficient matrix to implement the simultaneous measurement of temperature and strain. The experimental results demonstrate that the AR effect and MZI correspond to strain sensitivities of –0.87 and –2.29 pm/µε, respectively, and temperature sensitivities of 15.68 and –13.93 pm/°C, respectively. Furthermore, the sensor is also tested for repeatability, and the results show that it has good repeatability and great potential in sensing applications.

“…The spectral characteristics of antiresonant reflective optical waveguide (ARROW) are mainly determined by the thickness of the high refractive index layer of optical waveguide, which is considered as a Fabry-Perot (F-P) etalon. [1][2][3] It has received widespread attention in the field of near-infrared light signal transmission. The ARROW mode in hollow-core fiber (HCF) has been widely studied and applied in the field of fiber optic sensing, and many high-performance fiber optic sensors have been prepared, such as temperature, [4][5][6] gas pressure, 7 curvature, 8 liquid level, 9 and humidity 10 fiber optic sensors.…”

A high sensitivity sensor is proposed to measure axial strain, magnetic field, and refractive index. Hollow‐core fiber (HCF) and single mode fiber (SMF) are fused together to form the “SMF–HCF–SMF,” then tapering HCF, and finally forming a sensor. The light in the sensor structure forms an antiresonant reflection optical waveguide mechanism. The sensor has particularly thin waist circumference, therefore the surface evanescent field of the sensor is easily affected by environmental parameters, making it particularly sensitive to environmental parameters. The axial strain sensitivity obtained by the sensor is as high as −31.87 pm/µε. The magnetic field sensitivity obtained by combining the sensor with magnetostrictive material Terfenol‐D in the range of 10–40 mT is 123.9 pm/mT. The sensor measures the refractive index of NaCl solution with a sensitivity of up to 2109.308 nm/RIU (RIU: refractive index unit). Additionally, the sensor has good stability and repeatability when measuring three physical quantities. The sensor has a compact structure, stable performance, simple manufacturing, and can measure multiple parameters in biochemical engineering, industrial structural health detection, and marine resource detection.
