Recently demonstrated efficient second harmonic generation in centrosymmetric silicon nanoparticles fabricated by an optimized laser printing technique is attributed to nanocrystalline structure of nanoparticles supporting the Mie resonances. Here we demonstrate that second harmonic from such nanoparticles can be generated and split as much as 14 meV at room temperature under femtosecond IR pulses revealing new functionalities of modern nanophotonics elements – all-dielectric nanoparticles.
