  • PHOSPHO-ALUMINO-SILICATE ERBIUM DOPED FIBER FOR EXTENDED L-BAND AMPLIFICATION
    Publication number: 20250128982
    Abstract: Fiber amplifiers for extending their gain bandwidth through an optimization of the host matrix using phosphorus/aluminum (P/Al) as glass modifier are provided. In one aspect, an optical glass fiber comprising an Erbium doped silicate is provided, where the optical glass fiber comprises P2O5 of greater than 6 mol %; and Al2O3 of between 1.5 and 6 mol %, where a molar percent ratio of the P2O5 and the Al2O3 is between 2 and 4. Further, in some cases, use of yttrium as an alternative co-dopant to ytterbium may be used.
