Coherent Energy Transfers between Orthogonal Radiant and Weakly Radiant Plasmonic Nanorod Resonators
Artikel i vetenskaplig tidskrift, 2015

The coherent couplings between plasmon modes have attracted significant research interest recently as they can dramatically modify the lightmatter interactions and have many applications such as sensor and metamaterial. In this work, the energy transfer properties in a radiant and weakly radiant plasmon mode coupled system are investigated in the time domain. The phase difference between the two modes is found to vary from p to 0 with wavelength, and it is about p/2 near the resonance. The plasmon energy transfers back and forth between the two modes, and the transfer cycles increase with the coupling strength. Therefore, the system can undergo from enhanced absorption to Fano resonance phenomena on the optical spectra. Furthermore, the total energy transfer efficiency from the radiant plasmon mode to the weakly radiant one is also studied, and it shows a FOrster resonance energy transfer (FRET)-like behavior.
