摘要：

An experimental demonstration of the optical Vernier effect (OVE) achieved by cascading tapered single-mode optical fibres (SMF28) is presented. The tapered optical fibres conform to a pair of Mach–Zehnder fibre interferometers (MZFIs) with slightly different free spectral ranges. Three different experiments with MZFIs in tandem were carried out to evaluate the OVE characteristics such as the magnification and free spectral range of the envelope. The displacement/curvature sensor exhibited a sensitivity of 0.069 nm/µm (∼84.2 nm/m−1) in the displacement/curvature range of 250–500 µm (∼0.12–0.24 m−1) with a magnification of 8.84. A brief comparison to other OVE-based curvature sensors is presented. © 2022 Elsevier Inc.
