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…
