Some 175 years ago Michael Faraday discovered magnetic circular birefringence, now commonly known as the Faraday effect. Sensing the magnetic field through the influence that the field has on light within the fiber optic sensor offers several advantages, one of them fundamental. These advantages find application in the measurement of electric current at high voltages by measuring the induced magnetic field, thus warranting application for this kind of fiber optic sensor (FOS) in future smart grids. Difficulties in designing and manufacturing high-performance FOSs were greatly alleviated by developments in optical telecommunication technology, thus giving new impetus to magnetometry based on the Faraday effect. Some of the major problems in the processing of optical signals and temperature dependence have been resolved, yet much effort is still needed to implement all solutions into a single commercial device. Artificial structures with giant Faraday rotation, reported in the literature in the 21st century, will further improve the performance of FOSs based on the Faraday effect. This paper will consider obstacles and limits imposed by the available technology and review solutions proposed so far for fiber optic sensors based on the Faraday effect.

“…Fiber twisting is a simple and versatile method of modification of fiber structure, which provides additional opportunities for controlling light propagation. Twisted fibers can be used in different applications of fiber optics-in particular, in sensors of current [1], torsion [2,3], temperature [4] in fiber lasers [5], circular polarizers, couplers [6], optical vortices generators [7][8][9], and converters [10]. The optical effects of twisting are also of great fundamental interest [11], especially in relation with orbital angular momentum studies and vortex beams [12].…”

Exact equations are obtained to describe the propagation of the cladding modes in twisted optical fibers. Numerical solutions of these equations are found, which demonstrate that the paraxial approximation is not accurate for the cladding modes. Propagation constants and field distributions for the eigen circularly polarized modes are calculated for the coreless and standard fibers under twist. The cladding modes are affected by twisting much stronger than the core mode, and their field profiles are distorted. The exact modes have a mismatch between the radial and azimuthal components of the fields and cannot be combined to form the LP modes. Twisting may result in a change of sensitivity of the fiber to the external medium, which can be important for sensing applications.

Fabrication and characterization of spun HiBi PCF fibers for current sensing applications

et al. 2014

View full text Add to dashboard Cite

In this paper three highly birefringent (HiBi) spun photonic crystal fibers (PCF) are fabricated and their performance are characterized for electrical current measurement. These fibers are tested by coiling them around an electric conductor using three distinct winding diameters with different turns. The results present a very good linear relation with the current and its sensitivity depends on the winding diameter and on the number of turns. For the larger winding diameter, the fiber with lower circular pitch had higher sensitivity and for the smaller winding diameter the best sensitivity result was for the fiber with higher circular pitch.
