Giant femtosecond optical nonlinearity of gold metamaterial nanostructures
We demonstrate that the magnitude and sign of the third-order nonlinear susceptibility of plasmonic metals can be controlled by nanostructuring. By patterning a gold film on the nanoscale to support a high quality plasmonic mode, enhancement of its two-photon absorption coefficient by two orders of magnitude is realized. With a response time of <115 fs, nonlinear gold metamaterials have potential applications in ultrafast optical limiting and all-optical data processing with terahertz bandwidth.

Abstract
We demonstrate that the magnitude and sign of the third-order nonlinear susceptibility of plasmonic metals can be controlled by nanostructuring. By patterning a gold film on the nanoscale to support a high quality plasmonic mode, enhancement of its two-photon absorption coefficient by two orders of magnitude is realized. With a response time of <115 fs, nonlinear gold metamaterials have potential applications in ultrafast optical limiting and all-optical data processing with terahertz bandwidth.
