Resonant propulsion of small nonresonant particles inside metal waveguides due to the formation of resonant states by the guided modes below their cutoffs has been predicted in the past. Here it is shown that stable resonant propulsion exists in hollow-core photonic crystal fibers, which are all-dielectric structures and are a major platform for various photonic applications. Specific features of the resonant propulsion are discussed together with the fiber design issues. The results may enable power-efficient transport of particles over long distances, particle sorting, and sensitive detection.
过去曾预测，由于低于截止频率的导模形成共振态，金属波导内的小非共振粒子会产生共振推进。本文表明，空心光子晶体光纤中存在稳定的共振推进，这种光纤是全介质结构，是各种光子应用的主要平台。文中讨论了共振推进的具体特征以及光纤设计问题。这些结果可能使粒子能够高效地远距离传输、进行粒子分选和灵敏检测。
