Abstract:
In this paper, a time-domain fast gated near-infrared spectroscopy system is presented. The system is composed of a fiber-based laser providing two pulsed sources and two fast gated detectors. The system is characterized on phantoms and was tested in vivo, showing how the gating approach can improve the contrast and contrast-to-noise-ratio for detection of absorption perturbation inside a diffusive medium, regardless of source-detector separation.

Les nanolasers PhC suscitent de plus en plus d'attention en raison de leur capacité unique à manipuler et à confiner la lumière à une très petite échelle. Leur empreinte réduite et leur seuil bas en font des candidats idéaux pour la réalisation de connexions optiques, répondant ainsi à la demande croissante en matière de vitesse de transmission des données et de consommation d'énergie. De plus, leur géométrie singulière permet de contrôler leurs propriétés d'émission spontanée.

Elle résulte du couplage cohérent spin-photon dû à l’interaction spin-orbite. Une description simplifiée de cet effet a été faite en tenant compte d’un système à huit niveaux couplés au champ laser.

Abstract:
Beginning with the discovery of graphene, two-dimensional materials have amassed a strong interest. Like graphene, transition metal dichalcogenides (TMDs) can be coaxed into atomically thin sheets which have some impressive properties. Unlike graphene, TMDs also has a change in their electronic band structure causing an indirect band gap to a direct gap transition in its monolayer form. Additionally, these materials lose their inversion symmetry as a monolayer. These unique properties make TMDs a strong candidate for being used in optoelect

Abstract:
AbstractAttosecond four-wave mixing spectroscopy is a relatively new technique for studying ultrafast dynamics of highly excited states with exquisite temporal precision and spectral resolution. The attosecond four-wave mixing technique, as described in this paper, uses non-collinear beam geometries of one attosecond pulse together with two optical pulses to obtain background-free, spatially isolated emission signals in the extreme ultraviolet range that directly resolve coherent dynamics in the time domain. This method is advantageous by avoiding the strong spectral modulations that often com

It is noted that the former (whoopee) method does not depend on wave-vector matching within a macroscopic sample and can be applied to single-chromophore systems. A version of four-wave mixing using spectral interferometry is outlined. The ranges of interpulse delay within which each of several contributing wave-packet overlaps may take nonzero values are identified. Time-versus-time WPI interferograms f
