摘要：

A novel high thulium concentration doping technique is proposed for shifting the gain band in thulium-doped fibre amplifiers (TDFAs). The gain peak shifts from 1473 to 1505nm when the Tm3+ concentration is increased from 2000 to 8000 ppm. The authors have achieved gains of > 18dB and a noise figure (NF) of < 7dB from 1480 to 1510 nm (30nm bandwidth) for a total pump power of 500mW.
