- W2003207773 abstract "Recent studies on optical properties of Tm<SUP>3+</SUP>-doped tellurite glasses are presented as candidate materials of 1.4 micrometers amplifier. Usually, non-oxide fiber hosts with lower phonon energy are required, because the initial <SUP>3</SUP>H<SUB>4</SUB> level is easily quenched in high-phonon-energy environment. However, the restriction is not so server as that of the Pr<SUP>3+</SUP>:<SUP>1</SUP>G<SUB>4</SUB> for 1.3(Mu) M amplifiers due to the moderate energy gap. The Judd-Ofelt analysis showed 96 percent quantum efficiency in a tellurite host. To overcome the problem of intensity amplified spontaneous emission of competitive 0.80micrometers transition from the initial <SUP>3</SUP>H<SUB>4</SUB> level, an Nd-doped cladding was proposed utilizing a strong absorption band. Improved emission was obtained as a result of radiative energy transfers between Tm<SUP>3+</SUP> and Nd<SUP>3+</SUP> ion. Also, the effect of codopants, such as Eu<SUP>3+</SUP>, Tb<SUP>3+</SUP>, Ho<SUP>3+</SUP>, on the lifetime of the Tm<SUP>3+</SUP>-levels was investigated for efficient population inversion between the <SUP>3</SUP>H<SUB>4</SUB> and <SUP>3</SUP>F<SUB>4</SUB>. The Ho<SUP>3+</SUP> showed the best selectivity in quenching effect. Owing to its quantum efficiency and better fiberizability than fluorides, the Tm-doped tellurite glass can be a potential candidate of the amplifier at the S<SUP>+</SUP>-band in the WDM telecommunication." @default.
