Paper Abstract
We propose an ultra compact optical fiber sensor integrating a Mach-Zehnder interferometer (MZI) in fiber Bragg
grating (FBG) for simultaneous refractive index (RI) and temperature measurement. By use of the resonant wavelength
of the FBG and the interference dip of the MZI, the RI and temperature of the surrounding medium can be
unambiguously determined. The interesting properties of the sensor include good operation linearity, extremely high RI
sensitivity up to ~9148 nm/RIU (RI unit) in the RI range between 1.30 and 1.325 and precise sensing location,
determined by the MZI cavity created.
