Intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings

Intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings

An intensity-modulated magnetic field sensor based on magnetic fluid and optical fiber gratings is proposed and experimentally demonstrated. The sensor is formed by a tilted-fiber Bragg grating (TFBG) coated by magnetic fluid (MF) and cascaded by a chirped-fiber Bragg grating (CFBG). Transmission of...
