Optical fiber magnetic field sensor based on magnetic fluid and microfiber mode interferometer

Optical fiber magnetic field sensor based on magnetic fluid and microfiber mode interferometer

A magnetic field sensor is proposed based on the combination of magnetic fluid (MF) and an optical microfiber mode interferometer (MMI). It is measured that the MMI is highly sensitive to ambient refractive index (RI) with a high sensitivity up to 16,539 nm/RIU while RI of the MF is changeable with...
