Cascaded plasmon resonant field enhancement in nanoparticle dimers in the point dipole limit
Cascaded field enhancement in silver dimer nanostructures is investigated using a dipole-dipole interaction model. Field enhancement spectra are evaluated as a function of the particle size difference and inter-particle spacing. We observe three distinct regimes of cascaded field enhancement: hindered cascading, multiplicative cascading, and the ultimate cascading limit, depending on the dimer ...
متن کاملTaking cascaded plasmonic field enhancement to the ultimate limit in silver nanoparticle dimers
Cascaded optical field enhancement in coupled plasmonic nanostructures has attracted significant attention because of field enhancement factors that dramatically exceed those observed in isolated nanostructures. While previous studies demonstrated the existence of cascaded enhancement, little work has been done to identify the requirements for achieving maximum field enhancement. Here, we inves...
متن کاملResonant waveguide field enhancement in dimers.
It is shown that a waveguide mode, which exists between metal dimer particles and does not cut off, produces an enhanced electric field and hence a mechanism for surface-enhanced Raman scattering. Structures can thus be designed that provide large average field enhancement over significant length scales.
متن کاملPlasmon Hybridization in Nanoparticle Dimers
We apply the recently developed plasmon hybridization method to nanoparticle dimers, providing a simple and intuitive description of how the energy and excitation cross sections of dimer plasmons depend on nanoparticle separation. We show that the dimer plasmons can be viewed as bonding and antibonding combinations, i.e., hybridization of the individual nanoparticle plasmons. The calculated pla...
متن کاملCascaded field enhancement in plasmon resonant dimer nanoantennas compatible with two-dimensional nanofabrication methods
Cascaded field enhancement is demonstrated in asymmetric plasmon resonant dimer nanoantennas consisting of shape-tuned ellipsoidal nanoparticles. The nanoparticles that make up the dimer have identical thickness, suggesting that the presented approach can be used to design cascaded dimer antennas compatible with standard two-dimensional top-down nanofabrication tools such as electron beam litho...
