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…

Coupled cavity-waveguide system based on topological corner state and edge state
Aoqian Shi, Bei Yan, Rui Ge +5
Topological corner state (TCS) and topological edge state (TES) have provided new approaches to control the propagation of light. The construction of topological coupled cavity-wav…
