Tellurite glass waveguide material: processing and characterization

摘要

Although the success of demonstrating tellurite glass as a waveguide material in many applications, including tellurite fiberization, Nd~(3+)-doped tellurite fiber laser, and 1.5 um ultra-broad band Er~(3+)-doped optical amplifier, the advance of tellurite is still necessary in the areas of improving the quality of waveguide and understanding the correlations among processing, structure, and desired property, such as nonlinearity, rare-earth spectroscopy, nanocrystalline doping, and microstructured holey fiber. In the paper, we report some initial experimental results on fiberization processing of KNbO_3-Na_2O-ZnOTeO_2 and Er_2O_3-WO_3-TeO_2 systems. The report, in particular, focuses on the thermal characteristics of these glasses.
