This paper primarily discusses the structural performance analysis of a single/double/quadruple tapered optical fiber (TOF) structure based on single-mode fiber (SMF) and multi-mode fiber (MMF). Furthermore, the TOF's performance, including its diameter distribution, transmitted intensity, and reproducibility, is also evaluated. According to the experimental results, it can be concluded that the quadruple TOF structure based on SMF has a higher density of evanescent waves (EWs) on the surface of the tapered area, which is essential for the fabrication of high-sensitivity optical fiber sensors. The structure proposed in this article is feasible, and it can be used for optical fiber sensing while offering significant practical and promising applications as well.
本文主要讨论了基于单模光纤（SMF）和多模光纤（MMF）的单/双/四重锥形光纤（TOF）结构的结构性能分析。此外，还评估了TOF的性能，包括其直径分布、传输强度和可重复性。根据实验结果，可以得出结论，基于SMF的四重TOF结构在锥形区域表面具有更高的倏逝波（EWs）密度，这对于制造高灵敏度光纤传感器至关重要。本文提出的结构是可行的，它可用于光纤传感，同时还具有显著的实际应用价值和广阔的应用前景。
