摘要

我们介绍了一种新型光纤：二氧化硅手性多芯微结构光纤（MOF），其特点是在拉丝过程中产生扭曲，并使用由掺杂 GeO2 的二氧化硅玻璃制成的支撑元件。研究考虑了纤芯预型制造的技术方面，以及拉伸扭曲 MOF 长度的具体实施特点。所述复杂光纤结构的技术可行性已得到证实。首次制造了硅六芯 MOF 的加长（50 米长）试验样品，其纤芯具有阶梯和分级指数轮廓，扭转度从 50 转/分钟到 500 转/分钟不等，并介绍了测量其基本特性的结果。

Silica Multicore Microstructured Optical Fibers with Induced Twisting

We present a new class of optical fibers: silica chiral multicore microstructured optical fibers (MOFs) characterized by twisting induced during the drawing process and the use of supporting elements made of GeO₂-doped silica glass. Technological aspects of core preform manufacturing, as well as specific features of the implementation of drawing the lengths of twisted MOFs, are considered. The technical feasibility of the described complex fiber-optic structure is confirmed. Extended (50 m long) pilot samples of silica six-core MOFs with step- and graded-index profiles of the cores and different twisting degrees from 50 to 500 rpm are manufactured for the first time, and the results of measuring their basic characteristics are presented.
