Ultrabroadband near-infrared emission profiling in multicore optical fibers doped with Er3+ and Yb3+/Tm3+/Ho3+ ions

Abstract This paper presents novel multicore fibers with broadband emission in the 1.4–2.1 μm range. Based on our previous work with barium gallo-germanate glasses and fibers, the 4 and 11-core fiber structures, each containing core glasses doped with Er3+ and Yb3+/Tm3+/Ho3+, were developed. Our eff...
