Topological polarization singularities induced by the non-Hermitian Dirac points
Jun Wang, Jie Liu, Peng Hu +2
A Dirac point in the Hermitian photonic system will split into a pair of exceptional points (EPs) or even spawn a ring of EPs if non-Hermiticity is involved. Here, we present a new…
General bound states in the continuum in momentum space
Qiao Jiang, Peng Hu, Jun Wang +2
Polarization singularities including bound states in the continuum (BICs) and circularly polarized states have provided promising opportunities in the manipulation of light waves.…
Bound States in the Continuum Based on the Total Internal Reflection of Bloch Waves
Peng Hu, Chongwu Xie, Qianju Song +4
A photonic-crystal slab can support bound states in the continuum (BICs) which have infinite lifetimes but embedded into the continuous spectrum of optical modes in free space. The…
Designing topological interface states in phononic crystals based on the full phase diagrams
Yan Meng, Xiaoxiao Wu, Ruo-Yang Zhang +8
The topological invariants of a periodic system can be used to define the topological phase of each band and determine the existence of topological interface states within a certai…
Topological phase transition and interface states in hybrid plasmonic-photonic systems
Lixin Ge, Liang Liu, Meng Xiao +5
The geometric phase and topological property for one-dimensional hybrid plasmonic-photonic crystals consisting of a simple lattice of graphene sheets are investigated systematicall…
Direct Observation of Valley-polarized Topological Edge States in Designer Surface Plasmon Crystals
Xiaoxiao Wu, Yang Meng, Jingxuan Tian +4
The extensive research of two-dimensional layered materials has revealed that valleys, as energy extrema in momentum space, could offer a new degree of freedom for carrying informa…
