HEAVY METAL ELEMENT CONTAINING TeO{sub}2-BASED GLASSES FOR DISCRETE RAMAN FIBER AMPLIFICATION

摘要

We describe a glass family based on the combination of TeO{sub}2 with heavy metal oxides of Nb, Ti, W. The glasses possess a high thermal stability, large negative dispersion, large Raman gain and broad Raman spectrum. They are thus potentially useful in a variety of specialty fiber applications.
