Abstract

Tellurite glasses optical fibers became promising for optical amplifiers due to its high rare earth ions solubility and very large amplification bandwidth. Among several tellurite glasses the TeO₂-WO₃-Na₂O-Nb₂O₅ system show one of the largest bandwidth. Our previous characterization of lifetime using the omega2, omega4, omega6, Judd-Ofelt parameters indicate a quantum efficiency maximum for 7500ppm Er³⁺ concentration. Therefore we decided to produce jointed Er³⁺ and Tm³⁺ single mode optical fibers with this glass system keeping the 7500ppm Er³⁺ concentration and varying the Tm³⁺ concentration from 2500ppm to 15000ppm. This single mode fiber was pumped by 120mW of the semiconductor laser at 790nm and we observed a flat ASE bandwidth from 1400 to 1570nm for the 5000ppm Tm³⁺ concentration.
