Abstract

This work presents a fabricated silica few-mode microstructured optical fiber (MOF) with a special six GeO2-doped core geometry, an outer diameter of 125 µm (that corresponds to conventional commercially available telecommunication optical fibers), and improved induced twisting up to 500 revolutions per 1 m (under a rotation speed of 1000 revolutions per meter with a drawing speed of ~2 m per minute). The article discusses some technological aspects and issues of manufacturing the above-described twisted MOFs with complicated structures and geometry as GeO2-doped silica supporting elements for them. We present results of some measurements performed for fabricated samples of chiral silica six-GeO2-doped-core few-mode MOFs with various orders of twisting and both step and graded refractive indexes of “cores”. These tests contain research on MOF geometrical parameters, attenuation, and measurements of the far-field laser beam profile.

具有诱导手性的六芯GeO2掺杂二氧化硅微结构光纤

这项工作提出了一种制造的二氧化硅少模微结构光纤（MOF），其具有特殊的六GeO2掺杂芯几何结构、外径为125µm（对应于传统的商用通信光纤），并改善了高达每1m 500转的诱导扭曲（在每米1000转的转速下，拉伸速度约为每分钟2米）。本文讨论了制造上述具有复杂结构和几何形状的扭曲MOFs作为其掺杂GeO2的二氧化硅支撑元件的一些技术方面和问题。我们介绍了对制备的具有不同扭曲阶数和“芯”阶跃折射率和梯度折射率的手性二氧化硅六-GeO2掺杂芯少模MOFs样品进行的一些测量结果。这些测试包括对MOF几何参数、衰减和远场激光束轮廓测量的研究。

期刊介绍： Fibers (ISSN 2079-6439) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications on the materials science and all other empirical and theoretical studies of fibers, providing a forum for integrating fiber research across many disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. The following topics are relevant and within the scope of this journal: -textile fibers -natural fibers and biological microfibrils -metallic fibers -optic fibers -carbon fibers -silicon carbide fibers -fiberglass -mineral fibers -cellulose fibers -polymer fibers -microfibers, nanofibers and nanotubes -new processing methods for fibers -chemistry of fiber materials -physical properties of fibers -exposure to and toxicology of fibers -biokinetics of fibers -the diversity of fiber origins
