Coexistence and manipulation of multiple singularities in a reconfigurable non-Hermitian metasurface
Xintong Shi, Yanjie Wu, Rui Zhou +6
Non-Hermitian frameworks extend conventional Hermitian physics, offering a powerful paradigm for describing open systems. Central to this field are various singularities within the…
Protected Transverse Electric Waves in Topological Dielectric Waveguides
Rui Zhou, Minglin L. N. Chen, Xingtong Shi +5
Waveguides are fundamental components in communication systems. However, they suffer from reflection and scattering losses at sharp routes or defects. The breakthrough in developin…
A topological gap waveguide based on unidirectional locking of pseudo-spins
Yan Ren, Hai Lin, Rui Zhou +3
Photonic topological insulators (PTIs) have been widely studied due to the robustness of energy transport via supported edge modes immune to structural disorder. In this work, a to…
Coherent perfect absorber and laser induced by directional emissions in the non-Hermitian photonic crystals
Zhifeng Li, Hai Lin, Rongxin Tang +5
In this study, we propose the application of non-Hermitian photonic crystals (PCs) with anisotropic emissions. Unlike a ring of exceptional points (EPs) in isotropic non-Hermitian…
Higher-order valley vortices enabled by synchronized rotation in a photonic crystal
R. Zhou, H. Lin, Y. Wu +4
Synchronized rotation of unit cells in a periodic structure provides a novel design perspective for manipulation of band topology. We then design a two-dimensional version of highe…
