Dual Mach–Zehnder Interferometer Based on Side-Hole Fiber for High-Sensitivity Refractive Index Sensing

Dual Mach–Zehnder Interferometer Based on Side-Hole Fiber for High-Sensitivity Refractive Index Sensing

A unique type of refractive index (RI) sensor is proposed using a dual Mach-Zehnder interferometer (MZI) structure based on side-hole fibers (SHFs). The MZI structure contains two single-mode fibers (SMFs), two coreless fiber (CLF) sections and an SHF section, which are spliced together in the order...
