All‐Dielectric Metasurfaces: Near‐Infrared Super‐Absorbing All‐Dielectric Metasurface Based on Single‐Layer Germanium Nanostructures (Laser Photonics Rev. 12(9)/2018)

In article number 1800076, Qiang Li and co‐workers propose an ultrathin (≈0.13 λ0) germanium nanoantenna‐based all‐dielectric metasurface. Its near‐unity absorption is realized by simultaneously excited electric dipole and magnetic dipole resonances inside each element. This design paves the way for...

Description
Summary:In article number 1800076, Qiang Li and co‐workers propose an ultrathin (≈0.13 λ0) germanium nanoantenna‐based all‐dielectric metasurface. Its near‐unity absorption is realized by simultaneously excited electric dipole and magnetic dipole resonances inside each element. This design paves the way for realizing next generation optoelectronic devices aimed for high‐speed photon detection and energy harvesting.
