Journal ArticleDOI
Probing the Ultimate Limits of Plasmonic Enhancement
Cristian Ciracì,Ryan T. Hill,Jack J. Mock,Yaroslav A. Urzhumov,Antonio I. Fernández-Domínguez,Stefan A. Maier,John B. Pendry,Ashutosh Chilkoti,David R. Smith +8 more
TL;DR: It is found that the dominant limiting factor is not the resistive loss of the metal, but rather the intrinsic nonlocality of its dielectric response, which has implications for the ultimate performance of nanophotonic systems.
Journal ArticleDOI
Probing the mechanisms of large Purcell enhancement in plasmonic nanoantennas
Gleb M. Akselrod,Christos Argyropoulos,Thang B. Hoang,Cristian Ciracì,Cristian Ciracì,Chao Fang,Jiani Huang,David R. Smith,Maiken H. Mikkelsen +8 more
TL;DR: In this paper, the orientation of dipole emitters in nanogaps plays a vital role in spontaneous emission enhancement factors of greater than 1,000, the largest observed to date.
Journal ArticleDOI
Controlled-reflectance surfaces with film-coupled colloidal nanoantennas
Antoine Moreau,Cristian Ciracì,Jack J. Mock,Ryan T. Hill,Qiang Wang,Qiang Wang,Benjamin J. Wiley,Ashutosh Chilkoti,David R. Smith +8 more
TL;DR: It is shown that the film-coupled nanocubes provide a reflectance spectrum that can be tailored by varying the geometry (the size of the cubes and/or the thickness of the spacer) and can be controlled at scales out of reach of lithographic approaches that are otherwise required to manipulate matter on the nanoscale.
Journal ArticleDOI
Plasmonic Waveguide Modes of Film-Coupled Metallic Nanocubes
J. Britt Lassiter,Felicia McGuire,Jack J. Mock,Cristian Ciracì,Ryan T. Hill,Benjamin J. Wiley,Ashutosh Chilkoti,David R. Smith +7 more
TL;DR: This work examines the plasmon modes associated with a silver nanocube positioned above a silver or gold film, separated by an organic, dielectric spacer layer, of particular interest due to the formation of waveguide cavity-like modes between the nanocubes and film.
Journal ArticleDOI
Control of radiative processes using tunable plasmonic nanopatch antennas.
Alec Rose,Thang B. Hoang,Felicia McGuire,Jack J. Mock,Cristian Ciracì,David R. Smith,Maiken H. Mikkelsen +6 more
TL;DR: This work tunes the plasmonic resonance of the nanostructure of colloidally synthesized nanocubes electromagnetically coupled to a metallic film, and demonstrates fluorescence enhancements exceeding a factor of 30,000 with detector-limited enhancements of the spontaneous emission rate.
