N2 - This study proposes an inline electric-arc induced Mach-Zehnder interferometer (MZI) in a thinned cladding fiber. The proposed MZI is used for refractive index (RI) sensing. At the diameter of 56 μm and the length of 18 mm, in the RI of 1.33481.3558, the sensitivity is ∼580 nm/RIU, that is about 20 times greater than those of taper-based MZI sensors. Temperature characteristics of the MZI are investigated in 50800 °C. It is demonstrated that the proposed MZI is a good choice for high-temperature harsh environment sensing.
