“…Highly birefringent (Hi-Bi) optical fibers and Hi-Bi microstructured, or Hi-Bi photonic crystal fibers are special optical fibers realized by introducing certain elements with special geometry and appropriate mechanical and optical properties ensuring the creation of a permanent and welldefined birefringence [1]. These kinds of fibers can be used as active parts of an optical fiber sensor of any physical quantity which significantly influences the fiber's birefringence [2][3][4][5][6][7]. In order to interpret the impact of the environment on the fiber's birefringence correctly, one has to know the dispersion of the birefringence of the fiber within the used spectral range, first.…”

In the paper there are presented results of an investigation of a group birefringence of a fabricated polarization maintaining highly birefringent optical fiber around the central wavelength 1550 nm. The value of group birefringence was determined in two experimental ways. The first experimental set-up uses a system based on fiber loop mirror and the second one is based on a standard polariscopelike geometry usually used for investigation of birefringence of any optically transparent anisotropic medium. In both cases the birefringence is determined by appropriate analysis of typical interference patterns measured by the particular setup. The measurement was performed for fiber samples with various lengths. Comparison between values obtained for various lengths of samples and resulting from interference patterns measured using different experimental set-ups shows a very good match.

“…By creating a non-circularly-symmetric light-field in a fiber, Yin et al (2017) [22,23] developed two MF-based magnetic-vector sensors by sandwiching a piece of double-clad photonic-crystal-fiber or a thin core fiber between two single-mode fibers with a lateral offset. In 2018, based on a similar mechanism, magnetic-vector sensing was achieved by Layeghi et al, who used a tapered Hi-Bi fiber inserted in a fiber loop mirror [24]. In 2019, Cui et al [25] and Lu et al [26] respectively proposed using a single-mode-fiber fused with capillary structure and an excessively tilted fiber grating to realize the sensing to the magnetic vector.…”

Magnetic Nanoparticles Functionalized Few-Mode-Fiber-Based Plasmonic Vector Magnetometer

In this work, we demonstrate a highly-sensitive vector magnetometer based on a few-mode-fiber-based surface plasmon resonance (SPR) sensor functionalized by magnetic nanoparticles (MNPs) in liquid. To fabricate the sensor, a few-mode fiber is side-polished and coated with a gold film, forming an SPR sensor that is highly sensitive to the surrounding refractive index. The vector magnetometer operates based on the mechanism whereby the intensity and orientation of an external magnetic field alters the anisotropic aggregation of the MNPs and thus the refractive index around the fiber SPR device. This, in turn, shifts the resonance wavelength of the surface plasmon. Experimental results show the proposed sensor is very sensitive to magnetic-field intensity and orientation (0.692 nm/Oe and −11.917 nm/°, respectively). These remarkable sensitivities to both magnetic-field intensity and orientation mean that the proposed sensor can be used in applications to detect weak magnetic-field vectors.

“…MF is a kind of stable colloidal liquid that consists of highly dispersed Fe3O4-based magnetic nanoparticles (MNPs). It exhibits outstanding magneto-optic properties, including the Faraday effect and the tuneable refractive index (RI) in the external magnetic field [1,4,5]. Taking advantage of these magneto-optical properties, a lot of MF based fiber-optic magnetometers using different fiber configurations are reported in the literature.…”

Aiming at the requirement of high precision and long life in tasks of mechanical and navigation industries, a highly sensitive and compact, magnetorheological fluid film-suspended nonadiabatic biconical tapered optical fiber interferometer-based vector magnetometer has been proposed and demonstrated in the manuscript. The reported magnetometer keeps the ability to detect the strength of the magnetic field and its direction in the 3D plane concurrently. Magnetically regulated effective index amendment is used to stimulate the higher order modes propagating in the cladding region of the ultrathin biconical fiber interferometer. Hence, the detection principle of the sensor depends on the changes in the effective indices of higher-order excited modes with respect to the applied magnetic field. The proposed magnetometer detects slight angular variations of -2° to +2° in the magnetic field over a broad range from 0 mT to 567 mT by using the azimuth-dependent anisotropic distribution of nanoparticles in the vicinity of the fiber-optic sensor arm. The reported sensor offers to its angular sensitivities of ~ ∓14.68 pm/mT, and ~ ∓11.79 pm/mT at minor inclinations of ∓1° and ∓2° whereas having its maximum sensitivity of ~ 16.48 pm/mT at 0°.
