The narrow emission of a single carbon nanotube at low temperature is coupled to the optical mode fiber microcavity using built-in spatial and spectral matching brought by this flexible geometry. A thorough cw time-resolved investigation very same emitter both in free space cavity shows an efficient funneling into together with strong enhancement corresponding Purcell factor up 5. At time, emitted photons retain sub-Poissonian statistics. By exploiting feeding effect on phonon wings, we...
Condensed-matter emitters offer enriched cavity quantum electrodynamical effects due to the coupling external degrees of freedom. In case carbon nanotubes a very peculiar between localized excitons and one-dimensional acoustic phonon modes can be achieved, which gives rise pronounced wings in luminescence spectrum. By an individual nanotube tunable optical micro-cavity, we show that this exciton-phonon is valuable resource enlarge tuning range single-photon source while keeping excellent...
The lack of a systematic definition intermittency in the power sector blurs use this term public debate: same source can be described as stable or intermittent, depending on standpoint authors. This work tackles quantitative adapted to sector, linked nature source, and not current state energy mix production predictive capacity.

We develop a theoretical frame to investigate the spectral dependence of brightness single-photon source made solid-state nanoemitter embedded in high-quality factor microcavity. This study encompasses cases localized excitons one-, two-, or three-dimensional matrix. The population evolution is calculated based on spin-boson model, using noninteracting blip approximation. find that (hereafter called efficiency) can be expressed analytically through free-space emission and absorption spectra...
At cryogenic temperatures, the photoluminescence (PL) spectrum of nano-emitters may still be significantly broadened due to interactions with environment. The interplay spectral diffusion (SD) and phonon broadening in this context is a debated issue. Singlewall carbon nanotubes (SWNTs) are particularly relevant system address topic as they show intense undergo high exciton-phonon coupling their one-dimensional geometry. Here, we investigate correlations between main line that wings SWNTs...
Carbon nanotubes have strong assets for future integrated single-photon sources since their working wavelength can easily be tuned to the telecom C band by choosing an appropriate diameter [1]. In addition, they show a pronounced antibunching both at low and room temperature[2,3]. Nevertheless, practical implementation of such source requires embed nanotube into micro-cavity in order funnel emitted photons specific mode (and possibly optical fiber) beat non-radiative recombination means...
Carbon nanotubes have recently proven to be promising nano-emitters for future single-photon sources in the telecom wavelengths [1,2,3]. Coupling nanotube a micro-cavity brings invaluable handle control emission, regarding rate, yield, directionnality and extraction. All those features are related so-called Purcell effect that results from interaction of quasi-two-level system with high Q low mode-volume optical cavity. In carbon though, situation is slightly more complex due intimate...

By tuning physical parameters such as pump power we investigate line-shape deformation several...
Carbon nanotubes have emerged as original single photon source in the near IR and telecom bands. To further control their emission rate directionality, individual carbon nanotube can be coupled to a high Q small mode volume cavity (Purcell effect). Due 1D geometry of nanotube, coupling between localized exciton acoustic phonon is particularly strong. This used an additional degree freedom emitters; it brings very rich physics involving non-markovian decoherence, tripartite coupling,...
