Renaut, Claude; Lang, Lukas; Frizyuk, Kristina; Timofeeva, Maria; Komissarenko, Filipp; Mukhin, I. S.; Smirnova, Daria; Timpu, Flavia; Petrov, Mihail I; Kivshar, Yuri; Grange, Rachel


We combine the field confinement of plasmonics with the flexibility of multiple Mie resonances by bottom-up assembly of hybrid metal-dielectric nanodimers. We investigate the electromagnetic coupling between nanoparticles in heterodimers consisting of gold and barium titanate (BaTiO3 or BTO) nanoparticles through nonlinear second-harmonic spectroscopy and polarimetry. The overlap of the localized surface plasmon resonant dipole mode of the gold nanoparticle with the dipole and higher-order Mie...[Show more]
