摘要

•SPP launch is enhanced by a spherical metal (au) or all-dielectric (Si) nanoantenna.•Spectral position of peak efficiency is related to Mie resonances of nanoantennas.•The enhancement originates from electric dipole and electric quadrupole modes.•The peak value of the energy conversion efficiency reaches up to 25%.
