    Abstract: In accordance with a plurality of embodiments of the present invention, exemplary systems and articles of manufactures are described herein that are configured to propagate a MM signal from a light source, such as an optical fiber assembly for propagating a multimode (MM) signal from a light source, the optical fiber assembly comprising a multicore fiber (MCF) having a fiber numerical aperture (NA) value, a first core diameter and a first outer diameter (OD), and a combiner including a taper fiber bundle (TFB) portion in communication with the MCF, and at least one pigtail portion in communication with the light source, wherein the combiner propagates the MM signal from the light source, the MM signal having a signal NA value that is less than the fiber NA value such that the MM signal underfills the at least one pigtail portion.

    Abstract: A high efficiency optical combiner minimizes core region distortions in the area where fusion splicing between an input tapered fiber bundle (or any other type of “cladding-less” input fiber) and output fiber are joined. The thickness of the output fiber's glass cladding layer in the splice region is reduced (if not removed altogether) so that a core-to-core splice is formed and any necked-down region where the glass flows to join the core regions (while also joining the outer diameters) is essentially eliminated. The reduction of distortions in the core region of the splice improves the transmission efficiency between an input tapered fiber bundle and output fiber, reaching a level of about 99%. This high efficiency optical combiner is particularly well-suited for applications where a number of pump sources are combined and applied as an input to a fiber laser or amplifier.

    Abstract translation: 高效率的光合并器将输入锥形光纤束（或任何其它类型的“无包层”输入光纤）和输出光纤之间的熔接连接在一起的区域中的核心区域失真最小化。 接合区域中的输出光纤玻璃包覆层的厚度减小（如果不完全去除），从而形成芯 - 芯接头和玻璃流动以连接芯部区域的任何颈缩区域（同时也 连接外径）基本消除。 接合芯芯区域中的失真减小提高了输入锥形光纤束与输出光纤之间的传输效率，达到了约99％的水平。 这种高效率光学组合器特别适合于将多个泵浦光源组合并应用于光纤激光器或放大器的输入的应用。
