| Outline of Final Research Achievements |
Nanostructured photonic devices are useful for generation of high-density light energy. In this study, we studied a tunable light control using micro-scale plasma. Although plasma is widely used in fabrication process such as etching and surface treatment, plasma can be generated and vanished only by applied voltage unlike other optical materials. Such drastic changes of the characteristics have potential for highly functional optical materials. Argon plasma can be formed when voltage of 400 V was applied to hollow cathode type microelectrodes with current of 2 mA. Optical properties of Au nanostructrues were modulated before and after microplasma excitation.
