摘要：

A novel method of using two pump wavelengths to achieve high gains and enhanced noise performance in the 1.6 mum Er3+ doped fibre amplifier is demonstrated. By launching 82 mW of power at 1.48 mum and up to 1 mW at 1-555 mum, a maximum gain of 31 dB is achieved at 1.57 mum with gains in excess of 24dB available between 1.57 and 1.605 mum. The noise figure is maintained below 5dB over this bandwidth, close to the theoretical minimum for a 1.48 mum pumped amplifier.
