Multipolar second-harmonic generation by Mie-resonant dielectric nanoparticles

Smirnova, Daria; Smirnov, Alexander I.; Kivshar, Yuri


By combining analytical and numerical approaches, we study resonantly enhanced second-harmonic generation by individual high-index dielectric nanoparticles made of centrosymmetric materials. Considering both bulk and surface nonlinearities, we describe second-harmonic nonlinear scattering from a silicon nanoparticle optically excited in the vicinity of the magnetic and electric dipolar resonances. We discuss the contributions of different nonlinear sources and the effect of the low-order...[Show more]
