Research Abstract

Optical fields can be confined and enhanced in a nanometric space by the use of metal nanostructures, which potentially create novel photochemical reaction fields and photoenergy conversion systems. As a basis toward achieving that, we visualized nanoscale optical field distributions in various metal nanostructures to reveal the optical characteristics, using a near-field optical microscope that enables a spatial resolution far beyond that of a conventional optical microscope. We obtained guidelines for designing nanostructures that efficiently generate and control enhanced localized optical fields.
