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…
