TL;DR: A novel magnetic field sensor using tilted fiber Bragg grating interacting with magnetic fluid is proposed and experimentally demonstrated, achieving magnetic field strength measurement within a range of 196 Gauss by monitoring extinction ratio of cladding mode resonance.

TL;DR: In this article, an intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings is proposed and experimentally demonstrated, where the sensor is formed by a tilted-fiber Bragg grating (TFBG) coated by magnetic fluid (MF) and cascaded by a chirped-fibered Bragg Grating (CFBG), and reflected optical power is modulated twice by the magnetic field and measurement is realized in reflection manner.

TL;DR: A simple and compact reflective refractometer based on a tilted fiber Bragg grating inscribed in an ultra-high photon-sensitive thin-core fiber is proposed and experimentally demonstrated.

TL;DR: A novel tilted fiber Bragg grating-based magnetic field sensor by incorporating magnetic fluid is proposed and experimentally demonstrated, based on the refractive index change of magnetic fluid with external magnetic field.

TL;DR: In this article, a power-referenced refractometer operating in reflection mode is proposed and experimentally demonstrated based on a tilted-fiber Bragg grating (TFBG) cascaded by a reflection-band-matched chirped-fibers grating, where the optical signal reflected by the CFBG passes twice through the TFBG that enhances sensitivity of the this article.
