“…Optical cavity coupled with magnetic material is other type. These magnetic sensors typically consist of WGM resonator combined with magnetostrictive materials, 17 – 24 where the external magnetic field causes mechanical force to change the transmission spectrum while being able to preserve a high Q-factor. The magnetic field induced strain of most magnetostrictive materials is very small usually less than several ppm/mT, 25 and bandwidth and sensitivity are limited by the extent to which magnetostrictive materials and WGM resonator are combined 18 …”

.High sensitivity magnetic sensing is proposed using a sandwich structure with polydimethylsiloxane (PDMS) flexible resonator as the core. The directional sensing feature is provided by the sandwich structure’s preset magnetic field. The small Young’s modulus of flexible material corresponds to larger variation, resulting in a highly sensitive magnetic response. In the unshielded environment, the experimental results demonstrate redshift sensitivity of 1.08 nm / mT and blueshift sensitivity of 1.12 nm / mT, which are attributed to a slight variation in the PDMS’s Young’s modulus. The directivity curve’s concave point has a depth of 34.6 dB. The minimum detectable magnetic field of 0.96 nT · Hz − 1/2 is achieved at 1.4 kHz.

“…For example, Zhang [24] et al reported a highly sensitive bidirectional magnetic field sensor by packaging an optofluidic micro-resonator filled with a magnetic fluid which achieved a maximum sensitivity of 304.80 pm/mT and a detection limit of 0.0656 mT. Guo [25] et al, from Harbin Institute of Technology reported a hollow microbubble resonator based on fixed Terfenol-D, which achieved a tunable Q factor of 2.07 × 10 5 by tuning the WGMs with magnetic fields and a magnetic field sensitivity of 0.081 pm/mT. Yu [26] et al, reported a microcapillary resonator combined with magnetostrictive materials, achieving a DC magnetic field sensitivity of 0.1703 dB/Oe through AC magnetic field modulation.…”

“…Although the magnetic fluid can provide a significant response to the applied magnetic field, the magnetic fluid usually affects the optical quality of the resonator, making the detection limit of the sensor lower. Another type is a resonator combined with a magnetic material, usually consisting of a WGM resonator and a magnetostrictive material [25,30,31], where an external magnetic field induces mechanical forces to modify the transmission spectrum while being able to maintain a high Q-factor. The magnetic-field-induced strain of most magnetostrictive materials is very small, typically less than a few ppm/mT [32], and the bandwidth and sensitivity are limited by the degree of combination of the magnetostrictive material and the WGM resonator.…”

High-sensitivity resonator magnetic sensing requires a significant magnetostrictive response, while the narrow linewidth mode of a high-Q resonator can provide a high-precision frequency resolution. Therefore, a polydimethylsiloxane (PDMS) flexible resonator with both a low Young’s modulus and high optical transmittance is an ideal platform for realizing high-sensitivity magnetic sensing. Based on the sandwich structure of the PDMS flexible resonator, the mechanism of the magnetic field sensitivity of the PDMS flexible resonator sandwich structure is studied, and the impact of changes in the refractive index and radius on the sensor device is analyzed. In order to optimize the sensitivity of the sensor, when an external magnetic field acts on the sandwich structure, the impacts of three aspects on the sensitivity of the sensor are simulated and analyzed: different coupling positions of PDMS flexible resonator, different radii, and PDMS mixing ratios. The trend of sensitivity change is obtained, and the physical explanation of the sensitivity trend is analyzed. By optimizing these three aspects, the magnetic field sensitivity is eventually calculated as 19.02 nm/mT. Based on the existing experimental conditions and the preparation technology of the PDMS flexible resonator, the measured magnetic field sensitivity is 4.23 nm/mT.

“…In recent years, the optical whispering gallery mode (WGM) resonator has shown enormous potential in sensing applications, such as biology [ 15 , 16 , 17 ], temperature [ 18 , 19 , 20 ], gas [ 21 ], humidity [ 22 ], laser [ 23 ], and magnetic field sensing [ 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. Compared with the traditional optical resonators, the WGM resonator possesses high quality factor (Q), small mode volume and long lifetime of quantum photons.…”

A kind of novel and compact magnetic field sensor has been proposed and investigated experimentally. The proposed sensor consists of a tapered single mode fiber coupled with a nanostructured magnetic fluid-infiltrated photonic crystal fiber, which is easy to be fabricated. The response of magnetic fluid to magnetic field is used to measure the intensity of magnetic field via whispering gallery mode. The magnetic field-dependent shift in resonance wavelength is observed. The maximum magnetic field intensity sensitivity is 53 pm/mT. The sensor sensitivity is inversely proportional to the thickness of the photonic crystal fiber cladding.
