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…
Orbital Angular Momentum Multiplexing in Highly Reverberant Environments
Xiaoming Chen, Wei Xue, Hongyu Shi +2
Previous studies on orbital angular momentum (OAM) communication mainly considered line-of-sight environments. In this letter, however, it is found that OAM communication with high…
Ultra-wideband Reflection-type Metasurface for Generating Integer and Fractional Orbital Angular Momentum
Ling-Jun Yang, Sheng Sun, Wei E. I. Sha
Vortex beams carrying orbital angular momentum are extensively studied owing to its potential to expand channel capacity of microwave and optical communication. By utilizing the Pa…
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…
