    Ultrabroadband near-infrared emission profiling in multicore optical fibers doped with Er3+ and Yb3+/Tm3+/Ho3+ ions by Jakub Markiewicz, Marcin Kochanowicz, Tomasz Ragiń, Piotr Miluski, Wojciech A. Pisarski, Joanna Pisarska, Marta Kuwik, Dominik Dorosz, Martin Leich, Matthias Jäger

    Published 2025-02-01
    “…The measured emission spectra of these fibers are described as a superposition of emission bands from each individual core, corresponding to the transitions of Er3+, Tm3+, and Ho3+ ions. Our method demonstrates the potential of emission profiling in multicore optical fibers as a new way to construct eye-safe broadband fiber sources.…”
