Abstract
In this communication some of our works on nonlinear (NL) photonics with metal-dielectric nanocomposites (MDNCs) will be reviewed. The optical response of the MDNCs was controlled by selecting the metal nanoparticles (NPs) composition, shape, density, and spatial arrangement, as well as by the appropriate choice of the NPs hosts. High-order nonlinearities, beyond the usually studied third-order nonlinearity, were characterized. The NL propagation of light was studied and the stability and guiding of spatial solitons were investigated. A procedure for optimization of all-optical switches, the upgraded operation of an optical amplifier in the shortwave infrared region (SWIR), the optical modulation based on the dynamic control of gold nanorods driven by an external electric field, and the study of a NL metasurface in the SWIR, will be described to exemplify possible applications of MDNCs.
