Optically variable devices (OVDs) are in tremendous demand as optical indicators against
the increasing threat of counterfeiting. Conventional OVDs are exposed to the danger of …

Nanoscopic chiroptics studies the spin-dependent asymmetric light–matter interactions at
the nanoscale, where the asymmetry can stem from the intrinsic properties of materials …

Photons with spin angular momentum possess intrinsic chirality, which underpins many
phenomena including nonlinear optics, quantum optics, topological photonics and …

Optical metasurfaces with high quality factors (Q-factors) of chiral resonances can boost
substantially light-matter interaction for various applications of chiral response in ultrathin …

Polarization plays a key role in science; hence its versatile manipulation is crucial. Existing
polarization optics, however, can only manipulate polarization in a single transverse plane …

We demonstrate that rotationally symmetric chiral metasurfaces can support sharp
resonances with the maximum optical chirality determined by precise shaping of bound …

The scientific effort to control the interaction between light and matter has grown
exponentially in the last 2 decades. This growth has been aided by the development of …

Futuristic holographic displays will essentially require broadband chiro‐optical effects for
medical imaging, virtual reality, smart security, and optical encryption. However …

The past few decades have witnessed growing research interest in developing powerful
nanofabrication technologies for three-dimensional (3D) structures and devices to achieve …

Tunable metasurfaces enable dynamical control of the key constitutive properties of light at a
subwavelength scale. To date, electrically tunable metasurfaces at near-infrared …
