We numerically investigated gap surface plasmon polaritons (GSPPs) for optical field enhancement. Our findings predict high surface-enhanced Raman scattering (SERS) enhancement factors for nanostructures, enabling advanced optical sensing applications.

Area of Science:

  • Nanophotonics and Plasmonics
  • Optical Spectroscopy
  • Materials Science

Background:

  • Gap surface plasmon polaritons (GSPPs) are crucial for enhancing optical fields at the nanoscale.
  • Localized surface plasmon (LSP) resonance and GSPP coupling contribute to field enhancement.
  • Surface-enhanced Raman scattering (SERS) relies on significant optical field amplification.

Purpose of the Study:

  • To numerically investigate optical field enhancement mediated by GSPPs.
  • To predict and analyze surface-enhanced Raman scattering (SERS) enhancement factors (EFs) for nanostructures.
  • To explore the influence of nanostructure geometry, dimensions, and surrounding medium on SERS EFs.

Main Methods:

  • Numerical simulations were employed to calculate optical field enhancement.

  • Analysis of field enhancement originating from LSP resonance and GSPP coupling.
  • Systematic simulation of SERS EFs for equilateral triangular nanostructures with varying parameters.

    • Main Results:

    • Optical field enhancement is significantly supported by GSPPs in nanostructures.
    • Predicted SERS enhancement factors (EFs) reach up to 10^11 for specific nanostructure designs.
    • SERS EFs are sensitive to nanostructure geometry, dimensions, and the dielectric environment.

    Conclusions:

    • The interplay of LSP resonance and GSPP coupling drives substantial optical field enhancement.
    • Equilateral triangular nanostructures exhibit potential for ultra-high SERS sensitivity.
    • These nanostructures are promising for developing highly sensitive SERS-active substrates for optical sensing.
