Abstract

Recent developments in the construction of Erbium-doped fibers have seen parallel progress in the measurement techniques to characterize these fibers. In this paper, we discuss a simple method of obtaining threshold power amplification of Erbium-doped fibers. The method can be used to measure the threshold power of this particular fiber. As a result, the predicted threshold power value is in very good agreement with the experimental results obtained. We have based our measurements of the amplified spontaneous emission on both the forward and the backward directions of the fiber axis. We also report on other parameters such as Erbium doping concentration, the spectrum of absorption, and cross sections, with the objective of obtaining data for comparison of predicted threshold amplification with actual threshold amplification, when the Erbium-doped fibers are used in laser systems.
