Surface plasmon amplification by stimulated emission of radiation in hyperbolic metamaterials
Vitaliy N. Pustovit, Augustine M. Urbas, David E. Zelmon
We study theoretically and numerically spasing conditions and optical dynamics of a composite hyperbolic metamaterial interacting with gain molecules. By combining Maxwell-Bloch eq…
Coulomb and quenching effects in small nanoparticle-based spasers
Vitaliy N. Pustovit, Augustine M. Urbas, Arkadi Chipouline +1
We study numerically the effect of mode mixing and direct dipole-dipole interactions between gain molecules on spasing in a small composite nanoparticles with a metallic core and a…
Cooperative amplification of energy transfer in plasmonic systems
Vitaliy N. Pustovit, Augustine M. Urbas, Tigran V. Shahbazyan
We study cooperative effects in energy transfer (ET) from an ensemble of donors to an acceptor near a plasmonic nanostructure. We demonstrate that in cooperative regime ET takes pl…
