Influence of fiber parameters to the erbium-doped fiber amplifier (EDFA) gain: A theoretical modeling

Abstract

This paper studies the theoretical analysis of erbium-doped fiber (EDF) amplification. The EDF amplification is investigated in order to understand its behavior and identify the relevant parameters that are used for formulating the amplification process related to spontaneous and stimulated emission. Results show that under certain condition, the selected fiber parameters such as fiber length, EDF pump power, signal power and pump direction would significantly contribute to the EDFA gain enhancement.
