AbstractThe effect of transversal design in Erbium-doped fiber amplifiers’ gain and noise figure performance is illustrated in this work. In this work, we investigate experimentally a single pass 980 nm pumped EDFA with partially doped Erbium core fiber (PDCF), which has the core partially doped with Erbium ions. Later, the enumerated results for PDCF are compared with a standard fully doped EDF, having similar Erbium ion doping concentration. The PDCF Amplifier gain and noise figure performance is studied against different pump power and signal power at different operating wavelengths. The noise figure indicates improvement due to reduced spontaneous emission from un-doped region of the core.
