In this work, fabrication techniques and optimization of single-mode fiber (SMF)- and multi-mode fiber (MMF)-based differently tapered optical fiber (TOF) structures are discussed. Further, taper characteristics such as diameter, transmitted intensity, and repeatability are analyzed. The results show that 25 µm TOF consists of lower transmitted intensity, meaning higher evanescent waves materialize at the tapered surface, which helps in suitable potential application of TOF as an optical fiber sensor.
在这项工作中，讨论了基于单模光纤（SMF）和多模光纤（MMF）的不同锥形光纤（TOF）结构的制造技术和优化。此外，还分析了诸如直径、传输强度和可重复性等锥形特性。结果表明，25 µm的TOF具有较低的传输强度，这意味着在锥形表面会形成更高的倏逝波，这有助于TOF作为光纤传感器的合适潜在应用。
