Mach–Zehnder Interferometer Based on Interference of Selective High-Order Core Modes


We report a unique Mach–Zehnder interferometer primarily based on interference of selective high-order core modes in few mode fibers (FMFs). The proposed interferometer consists of a bit of FMF sandwiched between single-mode fibers with tiny lateral core-offsets. The theoretical and experimental results indicate that the interference patterns are coupled between core modes LP21 and LP02. As a result of LP21 and LP02 both reside within the fiber core, few of the guided light will propagate outside the fiber through the evanescent wave, which makes the sensor insensitive to surrounding refractive index (RI). The experimental results show that the proposed structure features a high strain sensing sensitivity of 3.thirty five pm/ $mu varepsilon $ within the vary of 0–1000 $mu varepsilon $ at the wavelength of 1513 nm. RI insensitivity makes the device convenient for strain measurement in humid environment.
