摘要：

A technique is proposed for designing the gain spectrum in Er3+- doped fibre amplifiers. It uses an active fibre constructed by connecting two erbium-doped fibres with different host materials. An Er3+-doped SiO2-Al2O3 fibre and an Er3+-doped multicomponent fibre were connected to flatten the gain spectrum in the 1.55 mu m band. A flat gain spectrum was achieved in the 1.533-1.558 mu m bandwidth range with a signal gain of 26dB and a noise figure of less than 6dB.
