The fabrication of surface nanoscale axial photonics (SNAP) microresonators, utilizing the approach of electric arc discharge (EAD), is accomplished, achieving a precision at the angstrom level. This paper thoroughly investigates the effects that discharge intensity and discharge duration have on SNAP microresonators, respectively, through the manipulation of relevant discharge parameters. The results indicate that, within a specified range of discharge intensity, a linear relationship is observed between the effective radius variation (ERV) and the discharge intensity, characterized by a slope of 0.325 nm/intensity unit. As the discharge duration is extended, the ERV gradually increases, eventually reaching a saturation value, which is inherently determined by the discharge intensity. Additionally, as the discharge intensity (or time) continues to increase, a “convex–concave–convex” shape is observed on the fiber, providing a method for fabricating bat microresonators. These discoveries derived from our study contribute toward providing a strong foundation for the progressive enhancement and refinement of EAD-based SNAP fabrication techniques.

利用电弧放电制造表面纳米级轴向光子结构


利用电弧放电（EAD）方法完成了表面纳米级轴向光子（SNAP）微谐振器的制造，实现了埃级的精度。本文通过操纵相关放电参数，深入研究了放电强度和放电持续时间分别对 SNAP 微谐振器的影响。结果表明，在一定的放电强度范围内，有效半径变化（ERV）与放电强度之间呈线性关系，其斜率为0.325 nm/强度单位。随着放电持续时间的延长，ERV逐渐增加，最终达到饱和值，该饱和值本质上由放电强度决定。此外，随着放电强度（或时间）的不断增加，在光纤上观察到“凸-凹-凸”形状，这为制造蝙蝠微谐振器提供了一种方法。我们的研究得出的这些发现有助于为基于 EAD 的 SNAP 制造技术的逐步增强和完善提供坚实的基础。
