Abstract

The investigation of the nonlinear optical response of various Au nanostructures has been recently accomplished in our laboratory and some selected results concerning the nonlinear optical properties of these nanostructures will be presented and discussed. In particular, the third-order nonlinear optical response of nanometer thick Au films and Au nano-island films, both deposited on transparent dielectric substrates, are going to be presented and discussed. In addition, the nonlinear optical response of Au nano-clusters encapsulated in block copolymer micelles will be also presented and compared with the other nanostructures. In all cases, the influence of the morphological characteristics of these structures on the nonlinear optical response will be discussed.
