80 nm ultra-wideband erbium-doped silica fibre amplifier

The authors demonstrate a two band architecture for an ultrawideband erbium-doped silica fibre amplifier with a record optical bandwidth of 80 nm. To obtain a low noise figure and high output power, the two bands share a common first gain section and have distinct second gain sections.
