Abstract: The influence of intrinsic optical resonances of spherical Si nanoparticles on the second harmonic generation process was studied by numerical methods. An increase in the efficiency of the second harmonic generation process was found due to the resonant amplification of the incident electric field or the resonant phasing of the near field of the second harmonic due to the Mie resonances.

Keywords: second harmonic, silicon, spherical nanoparticles, Mie resonances.
