Two-dimensional (2D) materials including graphene, transition metal dichalcogenides, black
phosphorus, MXenes, and semimetals have attracted extensive and widespread interest …

Plasmonic nanostructures possessing unique and versatile optoelectronic properties have
been vastly investigated over the past decade. However, the full potential of plasmonic …

Stimuli-responsive geometric transformations endow metamaterials with dynamic properties
and functionalities. However, using existing transformation mechanisms to program a single …

Ten years ago, three teams experimentally demonstrated the first spasers, or plasmonic
nanolasers, after the spaser concept was first proposed theoretically in 2003. An overview of …

Skin-like soft optical metamaterials with broadband modulation have been long pursued for
practical applications, such as cloaking and camouflage. Here, we propose a skin-like …

Molecular plasmonics, the area which deals with the interactions between surface plasmons
and molecules, has received enormous interest in fundamental research and found …

We visualized negative refraction of phonon polaritons, which occurs at the interface
between two natural crystals. The polaritons—hybrids of infrared photons and lattice …

Superlenses made of plasmonic materials and metamaterials can image features at the
subdiffraction scale. However, intrinsic losses impose a serious restriction on imaging …

Innovative multiplexing technologies based on nano‐optics for anti‐counterfeiting have
been proposed as overt and covert technologies to secure products and make them difficult …

Previous programmable metasurfaces integrated with diodes or varactors require external
instructions for field programmable gate arrays (FPGAs), which usually rely on computer …
