Abstract

We present experimental results from second-harmonic generation studies of lithographically-prepared arrays of centrosymmetric gold nanorods, extending a previous treatment. The arrays serve as diffraction gratings, allowing control over the emission directions. The intrinsic radiation patterns from the nanoparticles are superimposed on the diffraction pattern, creating a unique angular distribution of second-harmonic light. The surface plasmon resonance mode of the particles is tuned to match the wavelength of the ultrafast Ti:sapphire excitation laser, dramatically enhancing the second-harmonic intensity but also increasing photodesorption effects. The details of the diffracted peak intensities depend sensitively on the geometry of the system and require a complex normalization of the data.
