Purcell-enhanced quantum yield from carbon nanotube excitons coupled to plasmonic nanocavities.

Yue Luo, +8 more
- 10 Nov 2017 - 
TL;DR: It is demonstrated that coupling nanotubes to plasmonic antennas can lead to large Purcell enhancement and corresponding increase in quantum yield as well as plAsmonic thermometry at the single molecule level.
Journal ArticleDOI

Near-unity quantum yield from carbon nanotube excitons coupled to plasmonic nanocavities

Yue Luo, +8 more
- 04 May 2017 - 
TL;DR: In this paper, a single-walled carbon nanotubes (SWCNT) is coupled with plasmonic nanocavities reaching deeply into the Purcell regime with FP=234 (average FP=76), near unity quantum yields of 70% (average 41%), and a photon emission rate of 1.7 MHz into the first lens.
Journal ArticleDOI

Restoring mode degeneracy in H1 photonic crystal cavities by uniaxial strain tuning

Isaac J. Luxmoore, +7 more
- 22 Mar 2012 - 
TL;DR: In this article, a uniaxial strain technique was used to tune the mode wavelengths of planar photonic crystal cavities with high precision, and it was shown that it is possible to use an externally applied strain to control the splitting of the modes of the H1 cavity.
Journal ArticleDOI

Incoherent control of optical bistability and multistability in a hybrid system: Metallic nanoparticle-quantum dot nanostructure

Gh. Solookinejad, +4 more
- 09 Aug 2018 - 
TL;DR: In this paper, the optical bistability and multistability properties of incident light on a unidirectional ring cavity consisting of a hybrid semiconductor quantum dot-metal nanoparticle system driven by coupling and incoherent pumping fields were discussed.
Journal ArticleDOI

Strong Acoustic Phonon Localization in Copolymer-Wrapped Carbon Nanotubes.

Ibrahim Sarpkaya, +5 more
- 08 Jun 2015 - 
TL;DR: It is demonstrated that the ultranarrow and phonon sideband-resolved emission spectra can be fully described by a model assuming extrinsic acoustic phonon localization at the nanoscale, which holds down to 6-fold narrower spectral line width compared to previous work.
