Paper Abstract

The prospect of using optical fiber amplifiers made of rare- earth doped glasses other than the very familiar silica glass opens new applications and new amplifications windows. A literature survey has been conducted in order to assess the current situation in regards to these alternative technologies. Clearly, despite the amount of efforts, the 1.3 micrometers spectral region is still looking for a more efficient candidate. So far, Pr3+-doped ZBLAN is the technology of choice, offering quantum efficiencies of about 1.5 percent only. On the other hand, the current 1.55 micrometers fiber amplifiers offer nearly unbeatable performances. Other than rare-earth silica fiber amplifiers, only fluoride and tellurite glasses rare-earth doped fiber amplifiers applications is currently in a prospective state, although the potential of these technologies is undeniable. In these cases, the huge step between bulk glass and fiber fabrication remains to be made and/or optimized.
