We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

The spin Hall effect (SHE) of light, as an analogue of the SHE in electronic systems, is a
promising candidate for investigating the SHE in semiconductor spintronics/valleytronics …

Manipulating the properties of the isofrequency contours (IFCs) of materials provides a
powerful means of controlling the interaction between light and matter. Hyperbolic …

Metasurfaces with strongly anisotropic optical properties can support deep subwavelength-
scale confined electromagnetic waves (polaritons), which promise opportunities for …

Scientists have known for more than a century that light possesses both linear and angular
momenta along the direction of propagation. However, only recent advances in optics have …

Metamaterials are artificial optical media composed of sub-wavelength metallic and
dielectric building blocks that feature optical phenomena not present in naturally occurring …

The photonic spin Hall effect (PSHE) plays an important role in both fundamental science
and precision metrology. In this paper, we theoretically propose a polarization-dependent …

Light propagates in various ways depending on environment, including uniform medium,
surface/interface and photonic crystals, which appears ubiquitously in daily life and has …

Controlling the flow of light with nanophotonic waveguides has the potential of transforming
integrated information processing. Because of the strong transverse confinement of the …

Optics naturally provides us with some powerful mathematical operations. Here, we
experimentally demonstrate that during reflection or refraction at a single optical planar …
