Resonance energy transfer and superradiance mediated by plasmonic nanowaveguides.

چکیده
We show how both the subwavelength confinement associated with surface plasmons and the one-dimensional character of plasmonic waveguides can be exploited to enhance the coupling between quantum emitters. Resonance energy transfer and the phenomenon of superradiance are investigated in three different waveguiding schemes (wires, wedges, and channels) by means of the Finite Element Method. We also develop a simplified model that is able to capture the main features of the numerical results.

A single nanoparticle-based sensor for hydrogen peroxide (H2O2) via cytochrome c-mediated plasmon resonance energy transfer.
Herein, we report a novel method for H2O2 detection based on a single plasmonic nanoprobe via cytochrome c (Cyt c)-mediated plasmon resonance energy transfer (PRET). Dynamic spectral changes were observed in the fingerprint quenching dip of a single plasmonic nanoprobe in response to changes in the redox state of Cyt c, induced by H2O2. Based on the changes in the spectral profile of the single...
متن کاملGuided Propogation Along Quadrupolar Chains of Plasmonic Nanoparticles
The employment of periodic arrays of plasmonic nanoparticles has been proposed by several groups for enhanced transmission or absorption and for realizing optical nanowaveguides. Generally, due to their small transverse dimensions, such linear arrays have been operated near their dipolar resonance. However, it has been recently shown that nanoscale plasmonic particles may also support higher-or...

Hybrid plasmonic waveguides have achieved rapid advancement in plasmonics, which has given rise to remarkable field enhancement, light harvest, light-transport capabilities, bridging the gap between electronics and photonics by routing and manipulating light at sub-wavelength regions and so on. However, the development of plasmonic waveguides is hindered by lack of devices that can adjust coher...

The effectiveness of photocatalytic processes is dictated largely by plasmonic materials with the capability to enhance light absorption as well as the energy conversion efficiency. Herein, we demonstrate how to improve the plasmonic photocatalytic properties of TiO2/Al nano-void arrays by overlapping the localized surface plasmon resonance (LSPR) modes with the TiO2 band gap. The plasmonic TiO...
متن کاملHighly nonparaxial spin Hall effect and its enhancement by plasmonic structures.
We present a new way to obtain large spin Hall effect of light (SHEL) in nonparaxial situations. We use near field of dipoles which contain all plane waves, both homogeneous and evanescent. We base SHEL on dipole-dipole interaction initiated energy transfer (FRET), which we further enhance using plasmonic platforms. The spin-orbit coupling inherent in Maxwell equations is seen in the conversion...
