title: Towards nonlinear plasmonic devices based on metallic nanorods.
abstract: The nonlinear optical properties of gold nanorod arrays have been studied with a two-colour continuously working (CW) pump-probe spectroscopy. The hybridization of the nanorod arrays with a nonlinear polymer (poly-3BCMU) has been investigated for the purposes of active photonic component design. The sensitivity of the plasmonic resonances of the hybrid nanostructured system to pump-induced changes in the refractive index of the polymer surroundings has been used to control the optical extinction of the array. Both reversible and non-reversible behaviour has been observed reflecting the combined effects from the third-order nonlinear response of the hybrid metallo-dielectric system and post-photopolymerization triggered reactions in the polymer.
