摘要

半导体芯光纤因其特殊的光电特性而受到广泛关注。由于纤芯和包层材料之间的性质差异, 制备高质量的半导体芯光纤比传统掺杂石英玻璃光纤更为困难。以锗芯光纤为研究对象, 通过有限元法, 模拟仿真了激光拉制锗芯光纤的动态过程, 研究了拉制过程中芯层锗和包层石英玻璃材料的流速差异, 以及不同拉丝速度对其流速差异的影响。仿真结果表明: 在预制棒颈缩区, 芯层锗和包层石英玻璃材料的流速差异最大, 且不同拉丝速度对预制棒芯层锗和包层石英玻璃材料的流速影响不同。

Abstract

Semiconductor core fiber has attracted more and more attention due to its special photoelectric characteristics. The drawing of the semiconductor core fiber is more complicated than the conventional silica fiber due to the difference in properties between the core and the cladding material. In this paper, the Ge-core fiber is taken as the research object, and the dynamic drawing process of the Ge-core fiber is simulated by the finite element method. The difference in flow rate between the core of germanium and the cladding of silica, and the effect of different fiber drawing speeds on this flow rate difference are studied. The simulation result shows that significant difference of the core and cladding flow rate is at the position of the neck-down region of the preform, and the different drawing speed has different effects on the flow rates of the Ge-core and the silica-cladding of the preform.
