| Outline of Final Research Achievements |
In this study, titanium nitride (TiN) thin films have been structured to the nanodot arrays for the purpose of achieving surface plasmon amplification by stimulated emission of radiation (spaser). Periodic TiN nanodot arrays with a pitch of 400 nm are successfully fabricated on sapphire substrates by using the combination of nanoimprint lithography and reactive ion etching. Optical transmission on a nanodot array (dot diameter: 250 nm, dot height: 160 nm, dot period: 400 nm) shows the presence of the collective plasmonic modes, where the surface plasmon polaritons are radiatively coupled through diffraction. Enhanced photoluminescence has been also observed for a phosphor layer combined with the nanodot array, suggesting that the present approach has a high potential for nanoscale light manipulation including the achievement of spaser.
