PROJECT TITLE :
Temperature Fiber Sensors Based on Mach–Zehnder Interferometer With Sturdy Structure
This paper presents a highly sensitive and in-line temperature fiber sensor based on Mach-Zehnder interferometer with material overlay. The sensor is made using a section of single-mode fiber sandwiched between a no-core fiber and a waist-enlarged taper and immersed in an exceedingly material with high thermo-optic coefficient. The experimental results indicated that a hot temperature sensitivity of 0.825 nm/°C was accomplished for surrounding material with the refractive index of ~1.forty five. The proposed sensor has various deserves of in-line applications, high sensitivity, straightforward fabrication, easy structure, compact size, and furthermore, the structure is sturdy due to its high mechanical strength.
