| Outline of Final Research Achievements |
The dark mode localized surface plasmon (LSP) cannot be excited by by plane light wave, but it can be excited when a dipole source is located adjacent to the LSP structure. This structure shows Fano resonance or Electromagnetically-induced-transparency (EIT).
This study aims at understanding the dark mode plasmonics, and considers the application of the dark mode plasmonics to biosensors. We have investigated simple Fano structures on the basis of FDTD analysis. The structure was experimentally fabricated and measured the performance for biosensing. As a result, we found that the i-shape structure is promising for Fano resonance with high refractive index resolution.
