  • The intensity profiles and polarization states bestowed upon a beam by topological photonic crystals are limited to the spatial symmetries that can be realized with the crystal lattice. Here, authors demonstrate plasmonic Dirac-vortex lasing with tailorable intensity and polarisation distributions, based on photonic mass vortices engineering.

  • Current approaches to distinguish topological phases from topologically-trivial phases have limited general applicability. Here, in a photonic-crystal context, the authors demonstrate that in trivial structures the bulk local density of states (LDOS) extends all the way to the edges and corners, while in topological structures the bulk LDOS actually avoids the edges and corners.

  • The quantum spin Hall effect is limited to one-dimensional lower boundary states which limits the possibilities for its exploitation in photonic devices. Here, the authors demonstrate a higher-order quantum spin Hall effect in a photonic crystal and observe opposite pseudospin corner states.

  • Here, the authors report the experimental realization of a 3D Wannier-type photonic HOTI, which hosts coexisting self-guided topological surface, hinge, and corner states in a single 3D tight binding-like photonic crystal.

  • By tuning the geometry of a two-dimensional sonic crystal, its one-dimensional helical edge states become gapped and zero-dimensional topological corner states emerge. The band topology is thus manifested in a hierarchy of dimensions.

  • The recent discovery of higher-order band topology in topological insulators has unveiled the hierarchical structure of topological band theory. This Perspective reviews this rapidly developing field and discusses future directions, including open challenges, future trends, synergy and its use in other fields and potential applications.

  • Higher-order topological phase appears as a pioneering topic, and together with the non-Hermiticity, brings broad attentions recently. The authors explore the interplay between the non-Hermiticity and hierarchical topological states in a non-reciprocal framework and show the flexible reconstruction of non-Hermitian higher-order topological states.
