A brief review of topological photonics in one, two, and three dimensions
Zhihao Lan, Menglin L. N. Chen, Fei Gao +2
Topological photonics has attracted increasing attention in recent years due to the unique opportunities it provides to manipulate light in a robust way immune to disorder and defe…
Coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with symmetry
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
We demonstrate the coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with symmetry, which is composed of three interlacing triangular subla…
Local orbital-angular-momentum dependent surface states with topological protection
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
Chiral surface states along the zigzag edge of a valley photonic crystal in the honeycomb lattice are demonstrated. By decomposing the local fields into orbital angular momentum (O…
First-principle calculation of Chern number in gyrotropic photonic crystals
Ran Zhao, Guo-Da Xie, Menglin L. N. Chen +3
As an important figure of merit for characterizing the quantized collective behaviors of the wavefunction, Chern number is the topological invariant of quantum Hall insulators. Che…
Pseudospin-Polarized Topological Line Defects in Dielectric Photonic Crystals
Menglin L. N. Chen, Li Jun Jiang, Zhihao Lan +1
Electromagnetic topological insulators have been explored extensively due to the robust edge states they support. In this work, we propose a topological electromagnetic system base…
Quasi-Continuous Metasurfaces for Orbital Angular Momentum Generation
Menglin L. N. Chen, Li Jun Jiang, Wei E. I. Sha
A quasi-continuous composite perfect electric conductor-perfect magnetic conductor metasurface and a systematic metasurface design process are proposed for the orbital angular mome…
