Er doped oxide nanoparticles in silica based optical fibres
Wilfried Blanc, Bernard Dussardier, M. C. Paul
Erbium doped materials are of great interest in optical telecommunications due to the Er3+ intra-4f emission at 1.54 ?m. Erbium doped fibre amplifiers (EDFA) were developed in sili…
Visible and near infra-red up-conversion in Tm3+/Yb3+ co-doped silica fibres under 980 nm excitation
David A. Simpson, Keith W. E. Gibbs, Stephen F. Collins +5
The spectroscopic properties of Tm3+/Yb3+ co-doped silica fibers under excitation at 980 nm are reported. Three distinct up-conversion fluorescence bands were observed in the visib…
Thulium environment in a silica doped optical fibre
Wilfried Blanc, Thomas Lee Sebastian, Bernard Dussardier +4
Thulium-doped optical fibre amplifiers (TDFA) are developed to extend the optical telecommunication wavelength division multiplexing (WDM) bandwidth in the so-called S-band (1460-1…
Optical Scar in a chaotic fibre
Valérie Doya, Olivier Legrand, Claire Michel +1
We propose to use a multimode optical fiber with a D-shaped cross section as a privileged system to image wavefunctions of a chaotic system. Scar modes are in particular the sub je…
