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 Er and Yb/Tm/Ho were developed. Our efforts have resulted in flat emission in 3 dB and 10 dB bands, achievable under excitation at 796 nm, 808 nm, 940 nm, and 980 nm. The measured emission spectra of these fibers are described as a superposition of emission bands from each individual core, corresponding to the transitions of Er, Tm, and Ho ions. Our method demonstrates the potential of emission profiling in multicore optical fibers as a new way to construct eye-safe broadband fiber sources.

摘要

本文介绍了在1.4 - 2.1μm范围内具有宽带发射特性的新型多芯光纤。基于我们之前在镓锗酸钡玻璃和光纤方面的工作，开发了4芯和11芯光纤结构，每个结构的纤芯玻璃都掺杂了铒以及镱/铥/钬。我们的努力使得在796nm、808nm、940nm和980nm激发下，能够在3dB和10dB带宽内实现平坦发射。这些光纤的测量发射光谱被描述为来自每个单独纤芯的发射带的叠加，对应于铒、铥和钬离子的跃迁。我们的方法证明了多芯光纤中发射轮廓分析作为构建人眼安全宽带光纤源的一种新方法的潜力。
