Abstract
A new technique for flat gain control over a large range of input power with 1.55 µm fluoride-based erbium-doped fibre amplifiers is reported. It relies on the monitoring of backward-propagating amplified spontaneous emission. This technique is promising for future multiwavelength systems, where signal power or channel number variations may occur.Keywords
