“…The advantages of this type of sensors are the small size and possibility to have various sensing elements in the same optical fiber, thus allowing optical multiplexing. Alloys using Terfenol-D have also been tested in microstructured fibers [51]. Recently another kind of sensors to detect magnetic fields has been proposed, where the sensor is based on magnetic fluid.…”

Abstract:The intrinsic advantages of optical sensor technology are very appealing for high voltage applications and can become a valuable asset in a new generation of smart grids. In this paper the authors present a review of optical sensors technologies for electrical current metering in high voltage applications. A brief historical overview is given together with a more detailed focus on recent developments. Technologies addressed include all fiber sensors, bulk magneto-optical sensors, piezoelectric transducers, magnetic force sensors and hybrid sensors. The physical principles and main advantages and disadvantages are discussed. Configurations and strategies to overcome common problems, such as interference from external currents and magnetic fields induced linear birefringence and others are discussed. The state-of-the-art is presented including commercial available systems.

“…The first fiber optic sensor for measurement of magnetic field by integrating a highly birefringent photonic crystal fiber (HiBi PCF) combined with a Terfenol-D epoxy resin composite material was reported by Quintero et al [51]. An in fiber modal interferometer was assembled by evenly exciting both eigenmodes of the HiBi PCF.…”

“…It is also an effective way for magnetic field detection through light field modulation in optical fiber. In recent years, some ways have been proposed, such as multimode fiber with sensitive film coating [15], PCF deposited with Terfenol particles [16], and optical fiber in combination with magnetic fluid (MF) [17,18]. MF is one kind of magnetic field-sensitive material and has many attractive magneto-optic properties, for example, birefringence property, Faraday property, and magnetic-induced RI tunability [19][20][21][22].…”

An all-solid waveguide array fiber (WAF) is one kind of special microstructured optical fiber in which the higher-index rods are periodically distributed in a lowindex silica host to form the transverse two-dimensional photonic crystal. In this paper, one kind of multidimensional microstructured optical fiber photonic device is proposed by using electric arc discharge method to fabricate periodic tapers along the fiber axis. By tuning the applied magnetic field intensity, the propagation characteristics of the all-solid WAF integrated with magnetic fluid are periodically modulated in both radial and axial directions. Experimental results show that the wavelength changes little while the transmission loss increases for an applied magnetic field intensity range from 0 to 500 Oe. The magnetic field sensitivity is 0.055 dB/Oe within the linear range from 50 to 300 Oe. Meanwhile, the all-solid WAF has very similar thermal expansion coefficient for both high-and low-refractive index glasses, and thermal drifts have a little effect on the mode profile. The results show that the temperatureinduced transmission loss is < 0.3 dB from 26°C to 44°C. Further tuning coherent coupling of waveguides and controlling light propagation, the all-solid WAF would be found great potential applications to develop new micro-nano photonic devices for optical communications and optical sensing applications.

“…Compared to electronic techniques employed in magnetic field detection, fiberbased magnetic field sensors have advantages of immunity to electromagnetic interference, small size, and low loss for long distance operation and so on [2]. For the present, various kinds of fiber-based magnetic field sensors have been reported including side-polished fiber Bragg grating (FBG) coated with thin film of iron or Terfenol-D [3,4], utilizing the Faraday effect in a highly terbium-doped fiber [5], multimode fibers with magnetic composite coating [6], a FBG for dynamic magnetic field detection exploiting magnetically induced circular birefringence [7], magnetic field sensors based on the integration of a high-birefringence photonic crystal fiber with a composite material made of Terfenol particles and an epoxy resin [8], etc.…”
