| Outline of Final Research Achievements |
Plasmonics is optical nanotechnology based on metallic materials. It can be applied to ultra-compact photonic devices beyond the diffraction limit of light.
In this research, we study generation, amplification or modulation of surface plasmon polariton (SPP) which is two-dimensional optical wave propagating on noble metal surface. We have realized efficient source or amplification of SPP by colloidal quantum dots arranged on a silver substrate. In addition, we have achieved the modulation of emission spectra by nanoelectromechanically tunable plasmonic nanowire.
