Light-emitting metasurfaces [PDF]
Nanophotonics, 2019 Abstract Photonic metasurfaces, that is, two-dimensional arrangements of designed plasmonic or dielectric resonant scatterers, have been established as a successful concept for controlling light fields at the nanoscale. While the majority of research so far has concentrated on passive metasurfaces, the direct integration of nanoscale ...

Graphene-based tunable coding metasurfaces in terahertz band
EPJ Applied Metamaterials, 2020 Two graphene-based tunable coding metasurfaces are proposed for beam steering in terahertz band. The coding metasurfaces are composed of the unit cell with a sandwich-like structure, which contains the top layer of anisotropic rectangular graphene ...

Plane-wave scattering by self-complementary metasurfaces in terms of electromagnetic duality and Babinet's principle [PDF]
, 2013 We investigate theoretically electromagnetic plane-wave scattering by self-complementary metasurfaces. By using Babinet's principle extended to metasurfaces with resistive elements, we show that the frequency-independent transmission and reflection are ...

Optics Express, 2022 We numerically study metasurfaces that incorporate electro-optic materials and show that they can achieve large amplitude and phase modulations across a distance that is a fraction of the operation wavelength. We show that the metasurfaces made of dielectric discs placed on a film of lithium niobate can exhibit three main types of resonances ...

All-Dielectric Metasurfaces with High-Fluorescence-Enhancing Capability
Applied Sciences, 2018 All-dielectric metasurfaces are an emerging subfield in photonics. Light-wave manipulation has been extensively explored in these metasurfaces. Although light–matter interaction has also been investigated in these metasurfaces, only a limited ...

Hunting for Monolayer Black Phosphorus with Photoluminescence Microscopy
PhotonicsMonolayer black phosphorus (BP) holds great promise for naturally hyperbolic polaritons and correlated states in rectangular moiré superlattices. However, preparing and identifying high-quality monolayer BP are challenging due to its instability and high

Plasmonic metagratings for simultaneous determination of Stokes parameters
, 2016 Measuring light's state of polarization is an inherently difficult problem, since the phase information between orthogonal polarization states is typically lost in the detection process.
