    Abstract

    Nanoparticle oligomers made of metallic and/or dielectric nanoparticles are able to support sharp Fano resonances originating from an interference of two resonant modes with different spectral width. For practical applications, it is necessary to have an approach for tuning the Fano resonances of a nanostructure after its fabrication. Herein, we demonstrate a novel type of reconfigurable hybrid metaldielectric (Au-Si) oligomers supporting fine-tunable magnetic Fano resonances. We present an expanded experimental results of the Fano resonance tailoring via femtosecond laser melting of the plasmonic parts at the nanoscale. We believe that our findings pave the way to realization of nanophotonic elements that can be adjusted after their manufacturing.
