“…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.

Simultaneous measurement of both magnetic field strength and temperature with a microfiber coupler based fiber laser sensor ABSTRACTIn this paper we propose and investigate a novel magnetic field sensor based of a ring erbium-doped fiber laser combined with a fiber Bragg grating and a Sagnac loop containing a microfiber coupler and magnetic fluid. In addition to the magnetic field sensing capability, the proposed structure can simultaneously provide temperature information. Thanks to the dualring structure of the MFC-Sagnac loop and the FBG-assisted resonant cavity, the output has two distinct laser peaks. Experimentally demonstrated magnetic field sensitivity of one of the laser peaks is 15 pm/mT in the magnetic field range from 0 to 100 mT. The spectral position of the second laser peak is independent on the magnetic field but shifts towards long wavelengths with a sensitivity of 13 pm/°C.

“…This magnetooptic effect has been used in conjunction with fiber optic technology to realize an assortment of magnetic field sensors. For instance, fiber sensors have been reported based on submerging a microfiber knot into a ferrofluid [2], dipping single-mode fiber (SMF) tapers into a ferrofluid, [3,4], using a ferrofluid as an outer cladding of an etched multimode (MM) fiber, a coreless multimode fiber in a SMF/MMF/SMF optical structure [5,6] or a fiber grating etched within a D-shaped fiber [7]. These sensors require complex modification of the basic commercial fiber optic structure.…”

Transmissive optical fiber magnetic field sensor based on ferrofluids

Abstract-A compact optical fiber magnetic field sensor is reported which relies on the magnetic field induced displacement of a ferrofluid lying in the gap between two single mode optical fibers (SMFs) that are aligned face to face. The ferrofluid displacement alters the coupling of light from the input optical fiber to the output optical fiber. When the applied magnetic field changes from 0 mT to 10 mT the optical attenuation changes from 0 dB to -28 dB.
