Emission Properties of YB^3＋／Er^3＋ Doped TeO2-WO3-ZnO Glasses for Broadband Optical Amplifiers
摘要
The YbS+/Er3+ doped TeO2-WO3-ZnO glasses were prepared. The absorption spectra, emission spectra and fluorescence lifetime of Era+ at 1.5μm, excited by 970 nm were measured. The influence of Er2Oa, Yb2Oa and Ohcontents on emission properties of Era+ at 1.5 μm was investigated. The optimum doping concentrations for Era+and Yba+ is around 3.34× 1020 ions/cma and 6.63×1020 ions/cma, respectively. The peak emission cross section is 0.83～0.87 pm2. With the increasing concentration of Yba+, the FWHM of Era+ emission at 1.5 μm in the glass increases from 77 nm to 83 nm. The results show that Yba+/Era+ doped meO2-Woa-ZnO glasses are promising candidate for Era+-doped broadband optical amplifier.
