Observation of Topological Corner State Arrays in Photonic Quasicrystals
Aoqian Shi, Yiwei Peng, Jiapei Jiang +8
Recently, the studies of topological corner states (TCSs) are extended from crystals to quasicrystals, which are referred to as higher-order topological quasicrystalline insulators…
Simple theoretical model for parity-time-symmetric metasurfaces
Jianlan Xie, Shaohua Dong, Bei Yan +4
Many new possibilities to observe and use novel physical effects are discovered at so called exceptional points (EPs). This is done by using parity-time (PT) -symmetric non-Hermiti…
Multifrequency and multimode topological waveguides in a Stampfli-triangle photonic crystal with large valley Chern numbers
Bei Yan, Yiwei Peng, Jianlan Xie +9
The multifrequency quantum valley Hall effect (QVHE) with a large valley Chern number has been realized to significantly improve the transmission capacity of topological waveguides…
High-Order Nonreciprocal Add-Drop Filter
Hang Li, Rui Ge, Yuchen Peng +4
Topological photonics have led to the robust optical behavior of the device, which has solved the problem of the influence of manufacturing defects and perturbations on the device…
Giant photonic spin Hall effect near the Dirac points
Wenhao Xu, Qiang Yang, Guangzhou Ye +4
The origin of spin-orbit interaction of light at a conventional optical interface lies in the transverse nature of the photon polarization: The polarizations associated with the pl…
Near-zero-sidelobe optical subwavelength asymmetric focusing lens with dual-layer metasurfaces
Jianlan Xie, Shengnan Liang, Jianjun Liu +2
The existing metasurfaces with ultrathin volume for asymmetric transmission were often constructed by metal with low efficiency in optical frequency, and could not realize the opti…
