Summary

Single nanoapertures in gold films significantly boost second-harmonic generation (SHG). Researchers used nonlinear microscopy to show that triangular shapes offer greater SHG enhancement than circular ones due to their noncentrosymmetric design.

  • Utilizing nonlinear microscopy with polarization resolution for SHG imaging.
  • Quantitative analysis of SHG signals from circular and triangular nanoapertures.

    • Main Results:

    • Single nanoapertures significantly enhance SHG compared to a bare gold film.
    • SHG enhancement in circular apertures depends on diameter, influenced by phase retardation and edge field effects.
    • Triangular nanoapertures demonstrate superior SHG enhancement over circular apertures.

    Conclusions:

    • Subwavelength nanoapertures are effective structures for enhancing nonlinear optical processes like SHG.
    • Nanoaperture geometry plays a critical role in dictating SHG enhancement efficiency.
    • The noncentrosymmetric nature of triangular nanoapertures contributes to their enhanced SHG performance.
