摘要：
光波的导引传输对于现代通信、信息处理和能源生成系统中的基于光的应用至关重要。传统上，在光纤等结构中引导光波主要通过全内反射实现。在周期性平台中，还可以利用多种其他物理机制来传输光波。然而，在不支持全内反射的情况下，于全介电、非周期性和被动构型中横向约束光仍然是一项挑战。在这里，我们提出了一种利用拉格朗日点奇异特性来捕获光的方法；拉格朗日点是一类特殊的平衡位置，类似于天体力学中负责捕获特洛伊小行星的平衡位置。这是在扭曲排列中实现的，其中光学科里奥利力即使在折射率景观散焦或完全平淡无奇的位置也会诱导出导引通道。这些发现可能对标准光波导方案之外产生影响，并可应用于声学、电子束和超冷原子等其他物理系统。
英文摘要：
The guided transmission of optical waves is critical for light-based applications in modern communication, information processing, and energy generation systems. Traditionally, guiding light waves in structures like optical fibres is predominantly achieved through the use of total internal reflection. In periodic platforms, a variety of other physical mechanisms can also be deployed to transport optical waves. However, transversely confining light in fully dielectric, non-periodic and passive configurations remains a challenge in situations where total internal reflection is not supported. Here, we present an approach to trapping light that utilizes the exotic features of Lagrange points, a special class of equilibrium positions akin to those responsible for capturing trojan asteroids in celestial mechanics. This is achieved in twisted arrangements in which optical Coriolis forces induce guiding channels even at locations where the refractive index landscape is defocusing or entirely unremarkable. These findings may have implications beyond standard optical waveguiding schemes and could also apply to other physical systems such as acoustics, electron beams and ultracold atoms.
