Abstract

This paper analyzes multi-pump Raman+EDFA hybrid amplifiers with pump recycling using an improved technique that optimizes the gain and ripple of the amplifier for wavelength division multiplexing (WDM) applications. This technique is based on the equalization of Erbium's gain spectrum by adjusting the flexible gain profile of a multi-pump Raman amplification stage. The residual Raman pump recycled by the Erbiumdoped section is used to increase power pump efficiency. Multi-channel simulated gain characterization of the hybrid amplifier recycling Raman pump, in terms of global gain, ripple, and noise figure, is presented. Different configurations of the Raman stage with single, two, three and four-pump lasers are analyzed. For 8 WDM input channels with two and three-pump lasers, ripple values have presented variation from 3 to 9 dB against 4.3 to 12.6 dB obtained with the previous method, depending on the input power and number of pumps. The ripple analysis have has shown that the proper selection of pump wavelengths and powers, enables the construction of broadband hybrid Raman+EDFA amplifiers with enhanced power conversion efficiency and high and flat gains.
