Article Synopsis
- - A hybrid cascade strain sensor that combines a Mach-Zehnder interferometer (MZI) and a Fabry-Perot interferometer (FPI) is proposed to tackle low extinction ratio and high temperature cross-sensitivity issues commonly found in strain sensors using the Vernier effect.
- - The design improves strain sensitivity to -649.18 and achieves a low temperature sensitivity of 5.76 pm/°C by utilizing a long single-mode fiber to separate the two interferometers and enhancing the FP cavity's active length.
- - The sensor also demonstrates magnetic field sensitivity of -7.53 nm/mT when paired with a Terfenol-D slab, showing its potential for various strain sensing applications.
