Main Results:

  • Achieved high resonant absorption of visible light.
  • Demonstrated efficient excitation with normally incident light.
  • Showcased control over resonant wavelength via cavity dimensions (width/depth).
  • Confirmed insensitivity to incident angle through simulations.

Conclusions:

  • Resistless nanoimprinting in metal (RNIM) is a viable method for fabricating high-fidelity metallic nanopatterns.
  • The plasmonic nanocavity chain supports localized metal-insulator-metal cavity modes.
  • Coupling of cavities creates a chain waveguide mode suitable for sensitive detection, such as surface-enhanced Raman scattering.
