A vector bending sensor based on hole-assisted three-core fiber Mach-Zehnder interferometer is presented. The sensor includes multi-mode fiber HATCF MMF structure embedded between two single-mode fibers. The wavelength of the interference peak can be used to identify the bending curvature and direction, with a maximum bending sensitivity of -28.726 nm/m(-1) at a direction of 220 degrees. Additionally, the sensor exhibits a temperature sensitivity of 44 pm/degrees C and is not affected by external refractive index.
A vector bending sensor based on hole-assisted three-core fiber (HATCF) Mach-Zehnder interferometer (MZI) is demonstrated. The sensor is composed of multi-mode fiber (MMF) HATCF MMF structure embedded between two single-mode fibers (SMFs). The bending curvature and direction can be identified by interrogating the wavelength of the interference peak, and the maximum bending sensitivity of -28.726 nm/m(-1) is obtained at the 220 degrees direction. In addition, the sensor has a temperature sensitivity of 44 pm/degrees C and is insensitive to the external refractive index (RI).
