Abstract Topological photonics is currently one of the most active research areas in optics and also one of the spearheads of research in topological physics at large. We are now more than a decade after it started. Topological photonics has already proved itself as an excellent platform for experimenting with concepts imported from condensed matter physics. But more importantly, topological photonics has also triggered new fundamental ideas of its own and has offered exciting applications that could become real technologies in the near future.

拓扑光子学：我们该何去何从？

摘要 拓扑光子学是目前光学最活跃的研究领域之一，也是整个拓扑物理研究的先锋之一。我们现在已经十多年了。拓扑光子学已经证明自己是一个很好的平台，可以用来实验从凝聚态物理引入的概念。但更重要的是，拓扑光子学本身也引发了新的基本思想，并提供了令人兴奋的应用，这些应用可能在不久的将来成为真正的技术。
