Journal ArticleDOI
Dielectric Meta-Reflectarray for Broadband Linear Polarization Conversion and Optical Vortex Generation
TL;DR: This work presents an alternative approach to plasmonic metasurfaces by replacing the metallic resonators with high-refractive-index silicon cut-wires in combination with a silver ground plane, and demonstrates optical vortex beam generation using a meta-reflectarray with an azimuthally varied phase profile.
Journal ArticleDOI
Nonlinear Fano-Resonant Dielectric Metasurfaces.

TL;DR: The Fano-resonant silicon metasurface results in strong near-field enhancement within the volume of the silicon resonator while minimizing two photon absorption and results in transmission modulation with a modulation depth of 36%.
Journal ArticleDOI
Circularly polarized light detection with hot electrons in chiral plasmonic metamaterials.
TL;DR: An ultracompact circularly polarized light detector that combines large engineered chirality, realized using chiral plasmonic metamaterials, with hot electron injection is reported that could lead to enhanced security in fibre and free-space communication, as well as emission, imaging and sensing applications for circularly polarization light using a highly integrated photonic platform.
Journal ArticleDOI
Hot Electron-Based Near-Infrared Photodetection Using Bilayer MoS2.
TL;DR: Sub-bandgap photocurrent originating from the injection of hot electrons into MoS2 as well as photoamplification that yields a photogain of 10(5) results in a photoresponsivity of 5.2 A/W at 1070 nm, which is far above similar silicon-based hot electron photodetectors in which no photo amplification is present.
Journal ArticleDOI
Dynamic transmission control based on all-dielectric Huygens metasurfaces
TL;DR: In this paper, the authors combine dielectric resonators with an epsilon-near-zero (ENZ) mode in a thin film to achieve active control over the transmittance amplitude.
