Integral imaging is a promising three-dimensional (3D) imaging technique that captures and
reconstructs light field information. Microlens arrays are usually used for the reconstruction …

Plasmonic metasurfaces, which can be considered as the two-dimensional analog of metal-
based metamaterials, have attracted progressively increasing attention in recent years …

The research and development of optical metasurfaces has been primarily driven by the
curiosity for novel optical phenomena that are unattainable from materials that exist in nature …

Conventional imaging systems comprise large and expensive optical components that
successively mitigate aberrations. Metasurface optics offers a route to miniaturize imaging …

Metasurfaces provide a versatile platform for manipulating the wavefront of light using planar
nanostructured surfaces. Transmissive metasurfaces, with full 2π phase control, are a …

Diffraction gratings disperse light in a rainbow of colors with the opposite order than
refractive prisms, a phenomenon known as negative dispersion. While refractive dispersion …

Integrated-resonant units (IRUs), associating various meta-atoms, resonant modes, and
functionalities into one supercell, have been promising candidates for tailoring composite …

Metamaterials are artificial structures with the ability to efficiently control light‐field, attracting
intensive attention in the past few decades. People have studied the working principles …

We present a computational framework for efficient optimization-based “inverse design” of
large-area “metasurfaces”(subwavelength-patterned surfaces) for applications such as multi …

Metasurfaces offer a unique platform to precisely control optical wavefronts and enable the
realization of flat lenses, or metalenses, which have the potential to substantially reduce the …
