Paper Abstract

An approximated technique to optimize the gain profile of multi-pump broadband hybrid amplifiers (Raman+EDFA) under residual pump recycling is applied to a WDM system. The Optimized hybrid amplifier configurations with multi-pumping were analyzed considering different number of input channels in order to check the global gain saturation and the changes in the global gain profile that occur due to signal-pump, signal-signal, and pump-pump interactions. This work extends the optimization of the gain profile from Raman+EDFA hybrid amplifiers and studies the signal-signal interactions, signal-pumping and pumping-pumping WDM systems. Multiple input channels allowed the gain characterization of the Raman+EDFA hybrid amplifier in terms of global gain, ripple, and noise figure considering applications for WDM systems.
