Abstract
An approximate technique to optimise the gain profile of multi-pump broadband hybrid amplifiers (Raman + Erbium Doped Fibre) under residual pump recycling is applied to a WDM system. The optimisation was focused on the global gain and its ripple factor for the hybrid amplifier. This work extends the optimisation of the gain profile from Raman + EDFA hybrid amplifiers and examines the signal-signal interactions, signal-pumping and pumping-pumping WDM systems. Multiple input channels enabled the gain characterisation of the Raman + EDFA hybrid amplifier in terms of the global gain, ripple and noise figure considering applications for WDM systems.
