Paper Abstract

A large signal model of an optically pumped Erbium-doped travelling wave fibre amplifier is presented, including the influence of excited state absorption. The maximum gain and optimal amplifier length are discussed, based on the intensity of pump, signal and amplified spontaneous emission. Special attention is given to the gain degradation depending on the mode distribution of the pump light, and noise figures of the amplifier is presented for co- and counter propagating pump light. Finally, the variation of calculated results towards changes in the values of measured constants is considered.
