Main Results:

  • A thousand-fold enhancement in SHG was observed in the SiN grating compared to a flat film.
  • The SHG conversion efficiency reached the order of 10^-8.
  • The enhanced performance is attributed to localized field enhancement and SiN's nonlinear properties.

Conclusions:

  • SiN resonant waveguide gratings are highly effective for enhancing nonlinear optical processes like SHG.
  • All-dielectric nanostructures provide a promising platform for efficient frequency conversion.
  • This work surpasses the performance of plasmonic nanostructures in SHG efficiency.
