Abstract

The effects of the pump laser on the nonlinear refractive index of the erbium-doped fiber amplifiers (EDFA) were studied. A theory for the nonlinear susceptibility in the presence of a pump laser in a quasi-two-state system was developed. Amplification was produced by optically pumping an absorption band to provide signal gain in the emission band. The nonlinear refractive index decreased due to decrease in the self-phase modulation strength. The change in the normalized nonlinear refractive index was plotted as a function of the power pump level.
