A comparative analysis of surface and bulk contributions to second-harmonic generation in centrosymmetric nanoparticles

Timbrell, Daniel; You, Jianwei; Kivshar, Yuri; Panoiu, NC


Second-harmonic generation (SHG) from nanoparticles made of centrosymmetric materials provides an effective tool to characterize many important properties of photonic structures at the subwavelength scale. Here we study the relative contribution of surface and bulk effects to SHG for plasmonic and dielectric nanostructures made of centrosymmetric materials in both dispersive and non-dispersive regimes. Our calculations of the far-fields generated by the nonlinear surface and bulk currents...[Show more]
