摘要：

A lanthanum codoped erbium fibre amplifer (La-Er/GeO2/SiO2) has been investigated by comparing such an amplifier with Al-Er/GeO2/SiO2 and Er/GeO2/SiO2 EDFAs. A gain of more than 35 dB at a wavelength of 1.535-mu-m was obtained for 1.48-mu-m pump power of 35 mW, which was the highest gain among them. The gain spectral profile was moderately flattened at around 1.552-mu-m and the gain peaks at 1.535 and 1.552-mu-m shifted 0.5-1 nm toward the shorter wavelength region.
