| Outline of Final Research Achievements |
This research aims to realize photo-patterning beyond diffraction limit by gap-mode plasmons. The structure consists of gold meta-atom arrays were fabricated by electron beam lithography. Consequently, the gold meta-atom arrays with a gap width of 28 nm were successfully fabricated in a large area through its drawing parameter optimizations. The sample exhibited a specific optical characteristics related to the plasmon-induced transparency, indicating the gap-mode plasmon might be excited in the gap configuration. We conducted the curing experiments to cure the ultraviolet curable resin by casting the resin on the gold meta-atoms, however, we have not observed any nano-patterns on the structure. Further optimizations in plasmonic structures and light intensity are required to realize our purposes. On the other hands, we have gotten several knowledges concerning these investigations, and we will carry out this topic continuously.
