Bound states in the continuum (BICs) are waves that remain localized even though they
coexist with a continuous spectrum of radiating waves that can carry energy away. Their very …

The rapid development of additive manufacturing has fueled a revolution in various research
fields and industrial applications. Among the myriad of advanced 3D printing techniques …

We reveal that metasurfaces created by seemingly different lattices of (dielectric or metallic)
meta-atoms with broken in-plane symmetry can support sharp high-Q resonances arising …

Subwavelength optical resonators made of high-index dielectric materials provide efficient
ways to manipulate light at the nanoscale through mode interferences and enhancement of …

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 development of classical and quantum information–processing technology calls for on-
chip integrated sources of structured light. Although integrated vortex microlasers have been …

The introduction of bound states in the continuum (BICs) to photonics has revolutionized the
way cavity design and light–matter interactions are thought about in general. BICs can have …

Metasurfaces based on resonant subwavelength photonic structures enable novel ways of
wavefront control and light focusing, underpinning a new generation of flat-optics devices …
