Dielectric metasurfaces supporting quasi-bound states in the continuum (qBICs) enable high field enhancement with narrow-linewidth resonances in the visible and near-infrared ranges. The resonance emerges when distorting the meta-atom’s geometry aw

The ability to encode different operations into a single miniaturized optical device is required to reduce the complexity and size of optical paths for light manipulation, which usually employs dynamic optical components, interferometric setups, and/

The development of a metasurface lens, which represents a flat optical element with subwavelength thickness, holds the potential for miniaturizing imaging systems. Nevertheless, the presence of aberrations poses a significant challenge for achieving

Optical microresonators with low quality factor (Q$Q$) can be efficiently excited by and scatter freely propagating optical waves, but those with high Q$Q$ typically cannot. Here, we present a universal model for resonators interacting with freely pr

Optical imaging systems, like microscopes, cameras, and telescopes, continue to expand the scope of human observation of the world. As one of the key indicators of imaging systems, the field-of-view (FOV) is often limited by coma aberration. Expandin
