摘要：

A novel three-stage amplification configuration with two intermediate gain equalisers is proposed to enlarge the bandwidth of erbium-doped fibre amplifiers. Seamless 3dB gain bandwidths of 57nm (1550-1607nm) with an erbium-doped silica fibre amplifier and t62nm (1540.5-1602.5nm) with an erbium-doped fluoride fibre amplifier have been achieved with this configuration.
