Journal ArticleDOI
Stimulated emission of surface plasmon polaritons
TL;DR: In this paper, the authors observed stimulated emission of surface plasmon polaritons propagating at the interface between a silver film and a film of optically pumped polymethyl methacrylate (PMMA) doped with rhodamine 6G (R6G) dye.
Journal ArticleDOI
The effect of gain and absorption on surface plasmons in metal nanoparticles
Mikhail A. Noginov,Guohua Zhu,Messaoud Bahoura,J. Adegoke,C. Small,Brandon Ritzo,Vladimir P. Drachev,Vladimir M. Shalaev +7 more
TL;DR: In this paper, the compensation of loss in metal by gain in interfacing dielectric has been demonstrated in a mixture of aggregated silver nanoparticles and rhodamine 6G dye, and an increase of the quality factor of surface plasmon resonance was evidenced by the sixfold enhancement of Rayleigh scattering.
Journal ArticleDOI
Compensation of loss in propagating surface plasmon polariton by gain in adjacent dielectric medium
Mikhail A. Noginov,Viktor A. Podolskiy,Guohua Zhu,M. Mayy,Messaoud Bahoura,J. Adegoke,Brandon Ritzo,K. Reynolds +7 more
TL;DR: In this article, the suppression of surface plasmon polariton propagating at the interface between silver film and optically pumped polymer with dye has been reported, which enables a variety of applications of active nanoplasmonics.
Journal ArticleDOI
Enhancement of surface plasmons in an Ag aggregate by optical gain in a dielectric medium
Mikhail A. Noginov,Guohua Zhu,Messaoud Bahoura,J. Adegoke,C. Small,Brandon Ritzo,Vladimir P. Drachev,Vladimir M. Shalaev +7 more
TL;DR: The observed compensation of loss in a metal by a gain in a dielectric medium in the mixture of an Ag aggregate and a Rhodamine 6G dye facilitates many applications of nanoplasmonics.
Journal ArticleDOI
Correction: Corrigendum: Single Molecule Investigation of Ag + Interactions with Single Cytosine-, Methylcytosine- and Hydroxymethylcytosine-Cytosine Mismatches in a Nanopore
TL;DR: The alpha-hemolysin nanopore provides a novel platform to study the metal ion-DNA interactions and could also serve as a direct detection method for nucleobase modifications.
