摘要：
A novel Mach–Zehnder interferometer(MZI) sensor based on multiple supermode interferences that can be used for dualparameter measurements of temperature and strain is proposed and demonstrated. The MZI is made by splicing a coupled four-core sapphire-derived fiber(FSDF) between two single-mode fibers, utilizing the differences in temperature response and strain response of different supermodes in the FSDF to realize the simultaneous measurement of the two parameters.Experimental results demonstrate that the proposed MZI can achieve up to 1600 με and 1000°C measurements with a temperature-strain cross-sensitivity of approximately 0.075°C/με.
