    Area of Science:

    • Optics and Photonics
    • Materials Science

    Background:

    • High-resolution imaging fibers are crucial for medical and industrial applications.
    • Current imaging fibers often rely on high refractive index contrasts, increasing manufacturing costs.
    • The development of cost-effective imaging solutions is an ongoing challenge.

    Purpose of the Study:

    • To fabricate high-resolution imaging fibers from readily available, low-cost telecommunications fiber preforms.
    • To demonstrate a fabrication method that minimizes crosstalk in multi-core fiber arrays.
    • To enable the creation of economically viable single-use disposable imaging fibers.

    Main Methods:

    • Utilizing multi-stacking techniques with arrays of different sized cores.
    • Manufacturing fiber preforms from commercially available telecommunications materials.
    • Designing a square array of cores to optimize imaging performance and reduce crosstalk.

    Main Results:

    • Successful fabrication of high-resolution imaging fibers.
    • Suppression of core-to-core crosstalk in the multi-core fiber array.
    • Achieved comparable imaging performance to commercial imaging fibers without high refractive index contrasts.

    Conclusions:

    • Low-cost telecommunications fiber preforms can be used to create high-performance imaging fibers.
    • The multi-stacking fabrication method effectively suppresses crosstalk.
    • This advancement facilitates the development of affordable, disposable imaging fiber technology.
