Over the last two decades, the capabilities of metasurfaces in light modulation with
subwavelength thickness have been proven, and metasurfaces are expected to miniaturize …

Augmented reality (AR) display, which superimposes virtual images on ambient scene, can
visually blend the physical world and the digital world and thus opens a new vista for human …

Exquisite polarization control using optical metasurfaces has attracted considerable
attention thanks to their ability to manipulate multichannel independent wavefronts with …

BACKGROUND Future high-performance portable and wearable optical devices and
systems with small footprints and low weights will require components with small form …

A meta‐lens is an advanced flat optical device composed of artificial antennas. The
amplitude, phase, and polarization of incident light can be engineered to satisfy the …

We present a method allowing for the imposition of two independent and arbitrary phase
profiles on any pair of orthogonal states of polarization—linear, circular, or elliptical—relying …

Optical vortices (OVs) carrying orbital angular momentum (OAM) have attracted
considerable interest in the field of optics and photonics owing to their peculiar optical …

This article reviews recent progress leading to the realization of planar optical components
made of a single layer of phase shifting nanostructures. After introducing the principles of …

Metasurfaces, composed of specifically designed subwavelength units in a two-dimensional
plane, offer a new paradigm to design ultracompact optical elements that show great …

Compared with conventional optical elements, 2D photonic metasurfaces, consisting of
arrays of antennas with subwavelength thickness (the 'meta-atoms'), enable the …
