Molecular plasmonics, the area which deals with the interactions between surface plasmons
and molecules, has received enormous interest in fundamental research and found …

Metasurfaces are artificial two-dimensional (2D) planar surfaces that consist of
subwavelength'meta-atoms'(ie metallic or dielectric nanostructures). They are known for …

Nonlinear frequency conversion at the nanoscale is important for many applications in free
space and integrated photonics. In epsilon-near-zero (ENZ) materials, second-harmonic …

Plasmonic enhancement of nonlinear optical processes confront severe limitations arising
from the strong dispersion of metal susceptibilities and small interaction volumes that …

Metasurfaces have recently gained extensive interest because of their extraordinary optical
behavior as artificial material interfaces with ultrahigh compactness. In this framework …

Ultrafast nonlinearity, which results in modulation of the linear optical response, is a basis for
the development of time-varying media, in particular those operating in the epsilon-near …

Heavily doped semiconductors have emerged as tunable low-loss plasmonic materials at
midinfrared frequencies. In this article we investigate nonlinear optical phenomena …

Copper sulfide nanocrystals have recently been studied due to their metal-like behavior and
strong plasmonic response, which make them an attractive material for nanophotonic …

While free electrons in metals respond to ultrafast excitation with refractive index changes on
femtosecond time scales, typical relaxation mechanisms occur over several picoseconds …

We analyze the dynamics of vortex solitons and the formation of soliton clusters with
controllable attributes in a nonlinear metamaterial waveguide. We consider the nonlinear …
