“…The Bragg wavelengths of FBG do not change with the magnetic field, so the transmission intensity is determined by the SMF-NCF-SMF spectral shift. Due to the similar thermal effect of NCF and FBG, the cross-talk between temperature and the magnetic field is greatly reduced [68]. Pu et al proposed a magnetic field sensor by combining the microfiber coupling structures with MF.…”

Electromagnetic field sensors are widely used in various areas. In recent years, great progress has been made in the optical sensing technique for electromagnetic field measurement, and varieties of corresponding sensors have been proposed. Types of magnetic field optical sensors were presented, including probes-based Faraday effect, magnetostrictive materials, and magnetic fluid. The sensing system-based Faraday effect is complex, and the sensors are mostly used in intensive magnetic field measurement. Magnetic field optical sensors based on magnetic fluid have high sensitivity compared to that based on magnetostrictive materials. Three types of electric field optical sensors are presented, including the sensor probes based on electric-optic crystal, piezoelectric materials, and electrostatic attraction. The majority of sensors are developed using the sensing scheme of combining the LiNbO3 crystal and optical fiber interferometer due to the good electro-optic properties of the crystal. The piezoelectric materials-based electric field sensors have simple structure and easy fabrication, but it is not suitable for weak electric field measurement. The sensing principle based on electrostatic attraction is less commonly-used sensing methods. This review aims at presenting the advances in optical sensing technology for electromagnetic field measurement, analyzing the principles of different types of sensors and discussing each advantage and disadvantage, as well as the future outlook on the performance improvement of sensors.

“…In an environment without a magnetic field, Fe 3 O 4 nanoparticles are evenly distributed in the solution due to Brownian motion. When the magnetic field intensity increases, the nanoparticles form chain clusters along the direction of the magnetic field, thus changing the RI of the magnetic field [ 53 , 54 , 55 ]. The air gap introduces a phase shift in the FBG, and the magnetic fluid is injected into the gap.…”

As a special kind of Bragg grating, phase-shifted fiber Bragg grating (PS-FBG) has attracted extensive attention because of its extremely narrow transmission window and excellent sensing performance. The main purpose of this manuscript is to discuss the PS-FBG with special sensing characteristics and explore the influence of different inscription technologies on the sensing characteristics of PS-FBG by comparing the existing inscription methods. The sensing characteristics, advantages and disadvantages of PS-FBG with different structures are analyzed.

A novel multi-parameter sensor has been proposed based on the W-type leaky fibre grating, after the systematic investigation of its characteristics in response to the variation of temperature, surrounding refractive index and bend. The resonant wavelength for different mode in the reflection spectra has the same temperature sensitivity of ~9.13 pm/ o C, but the reflection intensity has no dependence upon the temperature change. The resonant wavelength of different mode linearly varies a little with the refractive index change, however, its reflection intensity follows the negative exponential decay with refractive index increasing, where for the higher modes the sensitivity is higher. The resonant wavelength for each mode almost linearly responds to the displacement, giving out a displacement sensitivity of 99.94 pm/mm. However, the reflection response to the displacement varies a lot. Based on these results, simple and compact multiparameter fibre sensors are proposed based on W fibre grating.
