Abstract:We demonstrate a method for fabricating a fiber sensor which is based on the Mach-Zehnder interference principle and used to the curvature sensing. By using of the CO2 laser fusion, a tandard single-mode fiber surface forms a collapse,
which is asymmetrical in the normal direction. When the core mode of the transmitted light enters the fusion region, a portion of the light will enter the cladding of the fiber and transport as cladding modes. The cladding modes are sensitive to the external environment and the deformations of the structure. When the cladding modes leave the fusion region, they
