| Research Abstract |
Surface plasmon can be activated when propagating light is incident on a metal nanostructure body. The surface plasmon is one of near-field light with resolution power beyond the diffraction limitation of the propagating light. If a material sample to be measured is put on the metal surface, the surface plasmon light propagates on the material surface. Since this propagation causes a phase shift in the surface plasmon light to be measured with a light interferometric method, refractive index profile or shape profile of the sample surface can be measured with a high accuracy of nano order. In order to reconstruct this surface plasmon interferometer, the following things are made clear: microfabrication method to generate nanoscale structures in a metal film, characteristics of surface plasmon excitation by metal nano pinhole, and fiber optical probe to extract plasmon with a high resolution.
