Second-harmonic generation (SHG) in metal nanoparticles is a promising new field combining nanotechnology with nanooptics [1]. Previous studies excellently proved the SHG effect of single nanoparticles attached preferentially to nonconductive surfaces. Similar to Raman scattering [2], the SHG efficiency can be considerably increased when coupling two such nanoantennas in the optical near-field region [3].
In the present study we investigate the generation of second-harmonic radiation from silver nanorod arrays as a function of different geometric parameters (volume, rod length, distance) including also the angle of incidence. Correlations between linear and nonlinear optical properties are found.
