1.2dB/cm gain in an erbium:lutecium co-doped Al/P silica fibre

By B.N. Samson, L. Dong, J.P. de Sandro and J.E. Caplen


We report a peak gain of 1.2dB/cm at 1535nm in an Erbium:Lutecium codoped Al/P/Si fibre fabricated using a standard MCVD and solution doping technique. This is the highest gain per unit length yet reported in an erbium doped fiber amplifier. The incorporation of lutetium into the glass is shown to reduce the erbium ion clustering within the fiber
