Bound states in the continuum (BICs) have attracted attention in photonics owing to their
interesting properties. For example, BICs can effectively confine light in a counterintuitive …

The manipulation of light has become the focus of various modern optical technologies. The
emergence of bound states in the continuum (BICs) offers an alternative platform for …

Bound states in the continuum (BICs) are peculiar discrete states embedded in the
continuous spectrum. It has been reported that BICs still exist and exhibit new features when …

We investigate the chiral spectral singularities, ie, laser threshold modes, in PT-symmetric
dielectric metasurfaces originating from quasi-bound states in the continuum. The poles …

Non-Hermitian photonic systems with loss and gain attract much attention due to their
exceptional abilities in molding the flow of light. Introducing asymmetry to the PT-symmetric …

We systematically study the spin Hall effect of light (SHEL) in the parity-time (PT)-symmetric
trilayer structure containing epsilon-near-zero (ENZ) materials, and design a high sensitivity …

The photonic spin Hall effect (PSHE) manifests itself as the spin-dependent transverse shift,
and has many applications including precise metrology and optical sensing. However, some …

Herein, we achieve giant Goos-Hänchen (GH) shifts driven by Fabry-Perot quasibound
states in the continuum (quasi-BICs) in double-layer gratings. Based on the hybrid coupling …

Exceptional points are the most intriguing features of non-Hermitian photonics, providing
clues for enhanced sensitivity, asymmetric light reflection, laser-absorber effect, topological …

To transform bound state‐in‐continuum (BIC)‐related unidirectional radiation into BIC‐
related unidirectional lasing, a 1‐D grating with a parity‐time (PT)‐symmetry configuration is …
