Super-luminescence and spectral hole burning effect in ultra-short length Er/Yb-doped phosphate fiber
Résumé
We demonstrate super-broad luminescence over 70 nm of bandwidth and spectral hole-burning effect obtained in just a few cm of novel air-clad, highly concentrated Er/Yb-doped phosphate fiber. The fiber is drawn from preforms of glasses within the P2O5 - SrO - Na2O composition. The fabrication process, thermal, structural, and optical properties of the fiber are described.
