    A novel micro-bending vector sensor was developed using grapefruit microstructure fiber (GMF) and single mode fiber (SMF). This fiber optic sensor accurately detects micro-bending with high sensitivity and is unaffected by surrounding refractive index changes.

    Area of Science:

    • Optoelectronics
    • Fiber Optics
    • Sensor Technology

    Background:

    • Micro-bending sensors are crucial for measuring physical parameters.
    • Existing sensors may suffer from environmental interference.
    • Developing robust and sensitive micro-bending sensors is an ongoing research area.

    Purpose of the Study:

    • To introduce a one-dimensional micro-bending vector sensor.
    • To investigate the sensor's performance under micro-bending.
    • To evaluate its immunity to surrounding refractive index and temperature crosstalk.

    Main Methods:

    • Fabrication of the sensor by laterally offset splicing a six-air-hole grapefruit microstructure fiber (GMF) with single mode fiber (SMF).
    • Investigating the variation of effective mode index due to micro-bending through simulation and experimental analysis.
