Extraordinary optical transmission (EOT) is a term that refers to electromagnetic resonances
through sets of subwavelength apertures in either a flat or a corrugated metal film, providing …

We present a study of the second-order nonlinear optical properties of metal-based
metamaterials. A hydrodynamic model for electronic response is used, in which nonlinear …

Second harmonic generation (SHG) with a material of large transparency is an attractive
way of generating coherent light sources at exotic wavelength range such as VUV, UV and …

We present a numerical investigation of the second-order nonlinear optical properties of
metal-based metamaterial nanoresonators. The nonlinear optical response of the metal is …

We show an alternative path to efficient second-and third-harmonic generation in proximity
of the zero crossing points of the dielectric permittivity in conjunction with low absorption …

High refractive index dielectric nanostructures can be exploited to enhance nonlinear optical
processes via the strong light confinement by their resonant modes. The sensitive …

Recent years have seen increased interest in the plasmonic enhancement of nonlinear
optical effects, yet there remains an uncertainty as to the limits of this enhancement. We …

Nonlinear frequency generation at the nanoscale is a hot research topic which is gaining
increasing attention in nanophotonics. The generation of harmonics in subwavelength …

We employ a classical, nonlinear Lorentz–Duffing oscillator model to predict third harmonic
conversion efficiencies in the ultrafast regime, from a variety of metal nanostructures …
