熔锥型光纤耦合器耦合比与拉伸长度的关系
Relationship between coupling ration and elongation length for fused tapered optical fiber couplers
摘要
Abstract
In order to explore the relationship between coupling ration and elongation length for fused tapered optical fiber couplers, the preset coupling ratio and the preset elongation length as the elongation stopping criterion were discussed, and also the regularities of distribution about the actual coupling ratio and elongation length were researched on the basis of the experiments about fused biconical taper. The results show that when the preset coupling ratio is treated as stopping criterion, the dispersion of actual elongation length is less than 0.5 mm; when the preset elongation length is treated as the stopping criterion, the dispersion of actual couping ratio increases from 1.13% to 21.16% with the increase of the elongation length. There is a linear relationship:y=177.3-6.5x, between the actual coupling ratio (y) and the elongation length (x) when the elongation length is undulate in 12.0 to 12.6 mm. This research provides the theoretical principle and supporting technology for improving and optimizing the manufacturing process and equipment in fiber baconical taper.关键词
