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.
