Enhanced Second-Harmonic Generation in AlGaAs Nanoantennas
Veröffentlicht in 2015
We designed AlGaAs all-dielectric nanoantennas with magnetic dipole resonance at near-infrared wavelengths. These devices are shaped as cylinders of 400nm height and radii varying from 175 nm up to 230 nm. We analyzed volume χ(2) nonlinear effects associated to a magnetic dipole resonance in these nanoantennas, and we predict second-harmonic generation from a single AlGaAs cylinder exceeding 10-3 efficiency with 1GW/cm2 of pump intensity.
