Experimental and Simulative Analysis of Cladding-Pumped EYDFA Gain Evolution

Signal gain evolution of a cladding-pumped single-core erbium-ytterbium co-doped fiber amplifier (EYDFA) at different doped fiber lengths is analyzed. The research is performed both experimentally and using a simulation model based on the measured signal parameters and EYDF characteristics. The results are compared to estimate the possibility of using such simulations for gain characteristics prediction prior to EYDFA experimental implementation.
