Considerably Enhanced Second-Harmonic Generation in Resonant U-Shaped Nano-Structures

In this paper, we perform a detailed study of the spectral response of the gold U-shaped nano-structures for different geometrical parameters and polarizations in order to obtain significant localization factor in the wavelength 1.55 μm. The obtained near-field distribution of electric fields reveals that resonances in these nano-structures correspond to the even and odd plasmonic modes dependi...

Plasmon-enhanced second-harmonic generation from ionic self-assembled multilayer films.

We have demonstrated large enhancements of the effective second-order nonlinear susceptibility (chi(2)) of ionic self-assembled multilayer (ISAM) films, causing a film with just 3 bilayers to be optically equivalent to a 700-1000 bilayer film. This was accomplished by using nanosphere lithography to deposit silver nanoparticles on the ISAM film, tuning the geometry of the particles to make thei...

Interface effects in plasmon-enhanced second- harmonic generation from self-assembled multilayer films

We have compared the plasmonic enhancement of second-order nonlinear optical (NLO) properties in two types of ionic self-assembled multilayer (ISAM) films combined with Ag nanoparticles fabricated using nanosphere lithography (NSL). The light-concentrating properties of the Ag particles lead to a marked increase in the NLO efficiencies of thin ISAM films. The induced enhancement is found to be ...
