“…We have already studied these structures simulating their nonlinear optical properties and effects of roughness. The latter have been explored experimentally as well [36,37]. Therefore, we deemed this metasurface to be well-suited for studying the interplay of electric and magnetic resonances.…”

Plasmonic resonances in metallic nanostructures have been shown to drastically enhance local electromagnetic fields, and thereby increase the efficiency of nonlinear optical phenomena, such as second harmonic generation (SHG). While it has been experimentally observed that enhanced fields can significantly boost SHG, to date it proved difficult to probe electrical and magnetic resonances in one and the same nanostructure. This however is necessary to directly compare relative contributions of electrical and magnetic components of SHG enhancement. In this paper we report an experimental study of a metasurface capable of providing electrical and magnetic resonant SHG enhancement for TM polarization. Our metasurface could be engineered such that the peak frequencies of electrical and magnetic resonances could be adjusted independently. We used this feature to distinguish their relative contributions. Experimentally it was observed that the magnetic resonance provides only 50% as much enhancement to SHG as compared to the electric resonance. In addition aligning both resonances in frequency results in conversion efficiency of 1.32 x 10 -10 .

“…and it was demonstrated that QPM in 2‐D NPC can be achieved for any direction aligned with a suitable reciprocal lattice vector. Since then, the 2‐D NPC and MM have been the subject of extensive studies, see, for example, [46–52] and references therein. The theoretical analyses in Refs.…”

“…The latter phenomenon usually originates from the wave interference at the microscopic level, which leads to suppression of the propagating spatial harmonics and formation of the bandgaps. The nonlinear properties of multilayered PhC and MM have been investigated mainly in connection to improving the efficiency of frequency conversion and harmonic generation [24–109].…”
