Higher-order topological states in photonic Thue-Morse quasicrystals: quadrupole insulator and a new origin of corner states
Langlang Xiong, Yu Zhang, Yufu Liu +2
Corner states (CSs) in higher-order topological insulators (HOTIs) have recently been of great interest in both crystals and quasicrystals. In contrast to electronic systems, HOTIs…
Topological properties of two-dimensional photonic square lattice without and symmetries
Langlang Xiong, Yufu Liu, Yu Zhang +2
Rich topological phenomena, edge states and two types of corner states, are unveiled in a two-dimensional square-lattice dielectric photonic crystal without both and $M_{x(y)…
Two Classes of Singularities and Novel Topology in a Specially Designed Synthetic Photonic Crystals
Qiucui Li, Yu Zhang, Xunya Jiang
Zak phase and topological protected edge state are usually studied in one-dimensional(1D) photonic systems with spatial inversion symmetry(SIS). Interestingly in this work, we find…
The Connection of Topology between Systems with Different Dimensions: 1D Zak Phases to 2D Chern Number, Weyl Point as the Jumping Channel for One Singularity and Nodal Line to Merge All Singularities
Qiucui Li, Xunya Jiang
The topology in different dimensions has attracted enormous interests, e.g. the Zak phase in 1D systems, the Chern number in 2D systems and the Weyl points or nodal lines in the sy…
Difficulties of the traditional PhC-based superprisms
Wei Li, Xiaogang Zhang, Xulin Lin +1
This paper is to discuss the difficulties of the traditional photonic crystals (PhC) -based superprisms.
Far-field super-resolution imaging with a planar hyperbolic metamaterial lens beyond the Fabry-Perot resonance condition
Cheng Lv, Wei Li, Xunya Jiang +1
We demonstrate achieving the far-field super-resolution imaging can be realized by using a planar hyperbolic metamaterial lens (PHML), beyond the Fabry-Perot resonance condition. A…
