“…In the influence of the magnetic field, the noncircular symmetry will further aggravate the nonuniform aggregation of MF around the fiber, and as a result, such sensors will be more sensitive to refractive index change. For this point, Hu et al [ 33 ] regarded that, a magnetic field sensor with a noncircular symmetric structure would have a good vector property. For instance, Yin et al [ 34 ] proposed a sensor based on the offset-core structure, by using PCF and MF.…”

“…Regarding the research results provided by Hu et al [ 68 ], Hyperbolic Metamaterials (HMMs) can improve SPR sensor sensitivity by reducing an equivalent dispersion. For this point, Hu et al [ 33 ] further proposed an SPR sensor based on HMMs which consists of alternating Au and ZrO 2 layers. Evanescent waves leak out from a side-polished surface and interact with HMMs and MF outside the fiber ( Figure 8 b), elevating a scaler sensitivity up to 1307 pm/Oe.…”

The magnetic field is a vital physical quantity in nature that is closely related to human production life. Magnetic field sensors (namely magnetometers) have significant application value in scientific research, engineering applications, industrial productions, and so forth. Accompanied by the continuous development of magnetic materials and fiber-sensing technology, fiber sensors based on the Magneto-Refractive Effect (MRE) not only take advantage in compact structure, superior performance, and strong environmental adaptability but also further meet the requirement of the quasi-distributed/distributed magnetic field sensing; they manifest potential and great application value in space detection, marine environmental monitoring, etc. Consequently, the present and prevalent Magneto-Refractive Magnetic Field Fiber Sensors (MR-MFSs) are briefly summarized by this paper, proceeding from the perspective of physicochemical properties; design methods, basic performance and properties are introduced systematically as well. Furthermore, this paper also summarizes key fabrication techniques and future development trends of MR-MFSs, expecting to provide ideas and technical references for staff engaging in relevant research.

“…In these FOSPR sensors, SPR on the outer surface of the metal film is excited by the principle of total internal reflection in fiber, enabling the realtime and highly sensitive detection of the ambient surroundings by demodulation of the optical signals such as wavelength, the intensity around the resonance wavelength, and others [9]. Moreover, various functional materials such as nanoparticles [10,11], multilayer metal/dielectric layers [12,13], graphene [14,15], and polymers [16] are integrated on the surface of FOSPR sensors to improve their sensitivity and tunability, further expanding their practical applications. In addition, tilted fiber Bragg grating SPR sensors [17][18][19], as another common FOSPR sensor, can achieve SPR on the outer surface of metal film without removing cladding by the diffraction effect of tilted grating, exhibiting a wide range of applications in various detection fields such as disease biomarkers, heavy metal pollution, and the like.…”

Fiber-optic surface plasmon resonance (FOSPR) sensing technology has become an appealing candidate in biochemical sensing applications due to its distinguished capability of remote and point-of-care detection. However, FOSPR sensing devices with a flat plasmonic film on the optical fiber tip are seldom proposed with most reports concentrating on fiber sidewalls. In this paper, we propose and experimentally demonstrate the plasmonic coupled structure of a gold (Au) nanodisk array and a thin film integrated into the fiber facet, enabling the excitation of the plasmon mode on the planar gold film by strong coupling. This plasmonic fiber sensor is fabricated by the ultraviolet (UV) curing adhesive transferring technology from a planar substrate to a fiber facet. The experimental results demonstrate that the fabricated sensing probe has a bulk refractive index sensitivity of 137.28 nm/RIU and exhibits moderate surface sensitivity by measuring the spatial localization of its excited plasmon mode on Au film by layer-by-layer self-assembly technology. Furthermore, the fabricated plasmonic sensing probe enables the detection of bovine serum albumin (BSA) biomolecule with a detection limit of 19.35 μM. The demonstrated fiber probe here provides a potential strategy to integrate plasmonic nanostructure on the fiber facet with excellent sensing performance, which has a unique application prospect in the detection of remote, in situ, and in vivo invasion.
