The development of new active optical fibre devices requires materials with " augmented " intrinsic properties, though using luminescent ion (LI) -doped silica as host glass. Optical fibers containing Dielectric Nanoparticles (DNP) grown by phase separation are proposed. DNP would optimally fully encapsulate LI to produce " engineered "...

Rare earth (RE) doped silica-based optical fibres with transparent glass ceramic (TGC) core were fabricated through the well-known modified chemical vapor deposition (MCVD) process without going through the commonly used stage of post-ceramming. The main characteristics of the RE-doped dielectric nanoparticles (DNP), their density and mean...

We report on using nanometric mass spectroscopy and molecular dynamics modelling to characterize the composition and structure of self-grown erbium-doped nanoparticles in transparent glass ceramic optical fibres fabricated by modified chemical vapour deposition without post-ceramming.

Glass-ceramics (considered here as a glassy host containing crystalline or amorphous nanoparticles) are of interest for luminescent properties as they can combine the sturdiness and low cost of a matrix host with particular spectroscopic behavior that would not appear in this host [1]. Ideally, nanoparticles would fully encapsulate luminescent...

(< 1500 characters): The study of amorphous phase-separated Dielectric Nano-Particles (DNPs) smaller than 10 nm is a great challenge for the materials community. In conjunction with Transmission Electron Microscopy (TEM) and Electron-Probe Micro-Analysis (EPMA), we took advantage of a recent technology, Tri-Dimensional (3D) Atom Probe...

Optical Backscatter Reflectometer (Luna OBR 4600 ) can transform a single mode fiber SMF in an efficient spatially distributed sensor of temperature and strain Unfortunately, t he operation field of OBR is limited to a single sensing fiber element . A parallel of multiple fibers is problematic as t he back scatter ed power to disc rimi nate is...
