Antichiral hinge states in a higher-order photonic nodal ring semimetal
Yuchen Peng, Deep Mondal, Yuting Yang +17
Antichiral states propagate in the same direction on opposite boundaries, defying the conventional constraint that boundary modes must cancel net chirality. Previously found antich…
Pseudospin-Induced Asymmetric Field in Non-Hermitian Photonic Crystals with Multiple Topological Transitions
Yuchen Peng, Aoqian Shi, Peng Peng +1
We report the discovery of multiple topological phase transitions induced by the photonic quantum spin Hall effect (PQSHE) in a non-Hermitian photonic crystal (PhC). When increasin…
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…
Frequency tunable topological edge states of two-dimensional honeycomb lattice photonic crystals
Yuchen Peng, Bei Yan, Jianlan Xie +5
In this paper, the photonic quantum spin Hall effect (PQSHE) is realized in dielectric two-dimensional (2D) honeycomb lattice photonic crystal (PC) by stretching and shrinking the…
