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 …

Optical metasurfaces are thin‐layer subwavelength‐patterned structures that interact
strongly with light. Metasurfaces have become the subject of several rapidly growing areas …

We observe enhanced third-harmonic generation from silicon nanodisks exhibiting both
electric and magnetic dipolar resonances. Experimental characterization of the nonlinear …

Nonlinear nanophotonics is a rapidly developing field of research with many potential
applications for the design of nonlinear nanoantennas, light sources, nanolasers, and …

This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

Phase matching is a critical requirement for coherent nonlinear optical processes such as
frequency conversion and parametric amplification. Phase mismatch prevents microscopic …

It is known that the nonlinear optical properties of photonic nanostructures can be modified
substantially due to strong field confinement and optical resonances. In this contribution, we …

Because of their ability to strongly localize and enhance optical fields, plasmonic
nanostructures have the potential to dramatically amplify the inherent nonlinear response of …

We perform third harmonic spectroscopy of dolmen-type nanostructures, which exhibit
plasmonic Fano resonances in the near-infrared. Strong third harmonic emission is …

Plasmonic nanorings provide the unique advantage of a pronounced plasmonic field
enhancement inside their core. If filled with a polarizable medium, it may significantly …
