In recent years intensive research has shown broadband luminescence in the range of 1100 to 1500 nm, across O, E and S bands of the telecommunications window from glasses or materials with Bi-doping and Bi/Er codoping. This presentation will report our research on active optical fibres based on new material compositions incorporating Bi, Er and Al into phosphogermanosilicate glasses. Emission and absorption are two main properties of active optical fibers that are of interest for fiber amplifiers and lasers. Hence, we report the recent development of Bi/Er/Al codoped phosphogermanosilicate optical fibres showing ultra broadband luminescence between 1000 and 1570 nm, covering O, E, S, C, and L bands, when pumped by 532, 808, or 980 nm lasers. This type of new material composition optical fibres is designed for potential use as an ultra broadband gain medium for ultra broadband amplified spontaneous emission (ASE) sources, tunable fibre lasers, or ultra broadband amplifiers in telecommunications and in other fields. © 2013 IEEE.
