Light can be tailored to carry angular momentum well beyond the restriction of its two spin
states, left-and right-circularly polarized light, by imbuing it with orbital angular momentum …

Recent rapid progress in metasurfaces is underpinned by the physics of local and nonlocal
resonances and the modes coupling among them, leading to tremendous applications such …

Control of the angular momentum of light at the nanoscale is critical for many applications of
subwavelength photonics, such as high-capacity optical communications devices, super …

We introduce a new paradigm for generating high-purity vortex beams with metasurfaces. By
applying optical neural networks to a system of cascaded phase-only metasurfaces, we …

Here we present a roadmap on Photonic metasurfaces. This document consists of a number

Metasurfaces are recently incorporated with waveguides for in‐plane wave manipulation
and extraction, enhancing the capability and design flexibility of integrated photonic devices …

Self-healing of light refers to the ability of a light field to recover its structure after being
damaged by a partial obstruction placed in its propagation path. Here, we will give a …

The appearance of quantized vortices in the classical “rotating bucket” experiments of liquid
helium and ultracold dilute gases provides the means for fundamental and comparative …

Replacing curved and bulky optical elements with thin and lightweight counterparts is a
persistent pursuit of the optical society. Metasurfaces, as two-dimensional artificial …
