Hybrid nanophotonics based on metal-dielectric nanostructures unifies the\nadvantages of plasmonics and all-dielectric nanophotonics providing strong\nlocalization of light, magnetic optical response and specifically designed\nscattering properties. Here we demonstrate a novel approach for fabrication of\nordered hybrid nanostructures via femtosecond laser melting of asymmetrical\nmetal-dielectric (Au-Si) nanoparticles created by lithographical methods. The\napproach allows selective reshaping of the metal components of the hybrid\nnanoparticles without affecting dielectric ones. We apply the developed\napproach for tuning of the hybrid nanostructures scattering properties in the\nvisible range. The experimental results are supported by molecular dynamics\nsimulation and numerical solving of Maxwell equations.\n
