Single-walled carbon nanotube/polystyrene core-shell hybrids: synthesis and photoluminescence properties

The formation of core-shell structures has permitted to improve greatly the emission properties of inorganic quantum dots. Single-Walled Carbon Nanotubes, thanks to their emission in the near infrared region, are promising materials for…

Ultra-low noise dual-frequency VECSEL at telecom wavelength using fully correlated pumping

An ultra-low intensity and beatnote phase noise dual-frequency vertical-external-cavity surface-emitting laser is built at telecom wavelength. The pump laser is realized by polarization combining two single-mode fibered laser diodes in a single-mode…

Synaptic plasticity modulation by circulating peptides and metaplasticity: Involvement in Alzheimer’s disease

Synaptic plasticity is a cellular process involved in learning and memory whose alteration in its two main forms (Long Term Depression (LTD) and Long Term Potentiation (LTP)), is observed in most brain patholo-gies, including neurodegenerative…

Fully–correlated multi–mode pumping for low–noise dual–frequency VECSELs

We report a fully-correlated multi-mode pumping architecture optimized for dramatic noise reduction of a class-A dual-frequency Vertical External Cavity Surface Emitting Laser (VECSEL). Thanks to amplitude division of a laser diode, the two…

Single photon emission from graphene quantum dots at room temperature

Graphene being a zero-gap material, considerable efforts have been made to develop semiconductors whose structure is compatible with its hexagonal lattice. Size reduction is a promising way to achieve this objective. The reduction of both dimensions…

Phase evolution of the direct detection noise figure of a nondegenerate fiber phase-sensitive amplifier

We experimentally investigate the evolution of the direct detection noise figure of a nondegenerate phase-sensitive amplifier based on a nonlinear fiber, as a function of the relative phase between the signal, idler, and pump, all other parameters…
