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 …

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 …

Recent research in topological photonics has not only proposed and realized novel
topological phenomena such as one‐way broadband propagation and robust transport of …

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 …

From theoretical model to experimental realization, the bound state in the continuum (BIC) is
an emerging area of research interest in the last decade. In the initial years, well-established …

Optical bound states in the continuum (BICs) underpin the existence of strongly localized
waves embedded into the radiation spectrum. Here we bring the concept of BICs to the field …

Metasurfaces are ushering in an era of multifunctional control over optical wavefronts
realized with ultrathin planarized devices. Recent advances have been enabling …

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

BACKGROUND Singularities are critical points for which the behavior of a mathematical
model governing a physical system is of a fundamentally different nature compared to the …

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 …
