Chromium-doped silica optical fibres : influence of the core composition on the Cr oxidation states and crystal field
Valérie Felice, Bernard Dussardier, Julian K. Jones +2
We have made chromium-doped, silica-based preforms and optical fibres by Modified Chemical Vapour Deposition and have studied the influence of the chemical composition of the doped…
Investigation of the photosensitivity, temperature sustainability and fluorescence characteristics of several Er-doped photosensitive fibers
Y. H. Shen, S. Pal, J. Mandal +7
Three different types of Er doped photosensitive fibers, germanium/erbium (Ge/Er) fiber, tin/germanium/erbium fiber (Sn/Er) and antimony/germanium/erbium fiber (Sb/Er) have been ma…
Large-mode-area leaky optical fibre fabricated by MCVD
Bernard Dussardier, Stanislaw Trzesien, Michèle Ude +3
A large mode area single-mode optical fibre based on leaky mode filtering was prepared by MCVD. The cladding structure discriminates the fundamental mode from the higher order ones…
In-Situ Grown Erbium-Doped Dielectric Nanoparticles in Silica-Based Transparent Optical Fibers
Bernard Dussardier, Wilfried Blanc, Valérie Mauroy +5
An efficient method to fabricate transparent glass ceramic fibers containing in-situ grown Er3+-doped oxide nanoparticles is presented. Characterization of the drawn fibers exhibit…
Energy transfer up-conversion in Tm3+-doped silica fiber
David A. Simpson, Gregory W. Baxter, Stephen F. Collins +4
A study of the mechanisms responsible for the infra-red to near infra-red up-conversion in Tm3+-doped silica fibers is presented. Upconversion luminescence was observed from the 3H…
Improvement of the Tm3+:3H4 level lifetime in silica optical fibres by lowering the local phonon energy
Basile Faure, Wilfried Blanc, Bernard Dussardier +1
The role of some glass network modifiers on the quantum efficiency of the near-infrared fluorescence from the 3H4 level of Tm3+ ion in silica-based doped fibres is studied. Modific…
