Three-dimensional optical metamaterial with a negative refractive index
Jason Valentine,Shuang Zhang,Thomas Zentgraf,Erick Ulin-Avila,Dentcho A. Genov,Guy Bartal,Xiang Zhang,Xiang Zhang +7 more
TL;DR: Bulk optical metamaterials open up prospects for studies of 3D optical effects and applications associated with NIMs and zero-index materials such as reversed Doppler effect, superlenses, optical tunnelling devices, compact resonators and highly directional sources.
Journal ArticleDOI
An optical cloak made of dielectrics
TL;DR: The optical 'carpet' cloak is designed using quasi-conformal mapping to conceal an object that is placed under a curved reflecting surface by imitating the reflection of a flat surface and enables broadband and low-loss invisibility at a wavelength range of 1,400-1,800 nm.
Journal ArticleDOI
Dielectric Optical Cloak
TL;DR: In this article, a dielectric optical cloak is designed using quasi-conformal mapping to conceal an object that is placed under a curved reflecting surface which imitates the reflection of a flat surface.
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
All-dielectric metasurface analogue of electromagnetically induced transparency
TL;DR: It is shown that the dielectric metasurfaces can be engineered to confine the optical field in either the silicon resonator or the environment, allowing one to tailor light-matter interaction at the nanoscale.
