文摘Optical fibers form one of the most mature and indispensable platforms in modern photonics.They underpin global telecommunications networks,enable high-power laser delivery and serve as the backbone of distributed sensing technologies.At the same time,the past decade has witnessed the rapid emergence of topological photonics[1],where concepts originating from condensed-matter physics-such as topological invariants,band inversion and defect-bound states-are used to engineer optical modes with intrinsic robustness.These ideas have led to striking demonstrations of topological photonics in platforms including photonic crystals,waveguide arrays,and microcavities.
