Observation of Chiral Bound States in the Continuum in Self-biased Magneto-optical Photonic Crystals
Maohua Gong, Qiutong Zhen, Yujie Tang +5
Chiral bound states in the continuum (BICs) are confined photonic modes with infinite quality factors and chiral response, offering significant potential for chiral optics. Althoug…

Topological polarization singularities induced by the non-Hermitian Dirac points
Jun Wang, Jie Liu, Peng Hu +2
A Dirac point in the Hermitian photonic system will split into a pair of exceptional points (EPs) or even spawn a ring of EPs if non-Hermiticity is involved. Here, we present a new…
