Abstract

We are studying the effects of localization of electromagnetic field and extension of plasmon lifetime on the near-field enhancement. In particular, the plasmon lifetime can be controlled by coupling with long-lived optical modes or excitons. In this study, we elucidated the near-field spectral characteristics and phase relaxation dynamics of coupled plasmonic nanostructures and the effect of plasmon dephasing dynamics on near-field enhancement.
