    Area of Science:

    • Photonics
    • Optical Fiber Technology
    • Sensor Technology

    Background:

    • Continuously twisted solid-core photonic crystal fiber (PCF) offers pure circular birefringence, crucial for Faraday effect-based sensors.
    • Optimizing PCF geometry is key to maximizing circular birefringence for improved sensor performance.

    Purpose of the Study:

    • To identify the optimal PCF geometry for maximizing circular birefringence.

    • To demonstrate the application of optimized twisted PCF in a DC current sensor.

    Main Methods:

    • Numerical analysis was employed to determine the optimal shape and scale parameters for PCF.
    • Experimental fabrication and testing of various PCF structures were conducted.
    • A DC current sensor was constructed using the optimized twisted PCF to measure Faraday rotation.

    Main Results:

    • The optimal shape parameter (diameter-to-spacing ratio) was found to be 0.37, and the scale parameter (spacing-to-wavelength) was 1.51 for silica-air PCF.
    • Numerical predictions were confirmed through experimental validation.
    • The twisted PCF sensor successfully measured Faraday rotation under varying DC currents.

    Conclusions:

    • The study successfully identified and validated an optimal PCF geometry for enhanced circular birefringence.
    • Optimized twisted PCF demonstrates significant potential for high-sensitivity current sensing applications.
    • The developed system allows for charting the wavelength dependence of the Verdet constant.
