Abstract :
Singlemode high erbium-doped phosphate glass fibres have been designed and fabricated. Gain measurements in a 2.15 cm fibre with an Er/sup 3+/ concentration of 3.7/spl times/10/sup 20/ rm/sup -3/ were performed. A net gain of 2.1 dB/cm at 1537 nm was demonstrated with a pump diode power of 110 mW at 980 nm.
