TÍTULO: “ Metal-Nanostructures for Nonlinear Photonics”

PALESTRANTE:  Prof. Cid Bartolomeu de Araújo (UFPE)

RESUMO: Nonlinear optical experiments with metal-nanoparticles and metal-nanoclusters hosted in dielectric liquids and glasses will be reported. The metal-dielectric nanocomposites produced were studied by selecting the nanostructures compositions, shapes, densities, and spatial arrangements, as well as by choosing appropriate hosts. Optical nonlinearities, beyond the third order, were observed and characterized. The stable propagation of spatial solitons was studied along with the guiding of light beams using optical vortices. A procedure for optimization of all-optical switches, the upgraded operation of optical amplifiers 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 metal-metasurface in the SWIR, will be described to illustrate possible applications of metal-dielectric nanocomposites.
