Optical skyrmions are an emerging class of structured light with sophisticated particle-like topologies with great potential for revolutionizing modern informatics. However, the current generation of optical skyrmions involves complex or bulky systems, hindering the development of practical applications. Here, exploiting the emergent "lab-on-fiber" technology, we demonstrate the design of a metafiber-integrated photonic skyrmion generator. We not only successfully generate high-quality optical skyrmions from metafibers, but also verify their remarkable properties, such as topology switchability and topology stability with subwavelength polarization features beyond the diffraction limits. Our flexible fiber-integrated optical skyrmions platform paves the avenue for future applications of topologically-enhanced remote super-resolution microscopy and robust information transfer.
光学斯格明子是一类新兴的结构化光，具有复杂的类粒子拓扑结构，在革新现代信息学方面具有巨大潜力。然而，当前一代光学斯格明子涉及复杂或庞大的系统，阻碍了实际应用的发展。在此，利用新兴的“光纤实验室”技术，我们展示了一种超纤维集成光子斯格明子发生器的设计。我们不仅成功地从超纤维中产生了高质量的光学斯格明子，还验证了它们的显著特性，如拓扑可切换性和具有超越衍射极限的亚波长偏振特征的拓扑稳定性。我们灵活的光纤集成光学斯格明子平台为拓扑增强型远程超分辨率显微镜和稳健信息传输的未来应用铺平了道路。
