Ma. Ali et al., OPTIMIZED PERFORMANCE OF ERBIUM-DOPED FIBER AMPLIFIERS IN MULTIWAVELENGTH LIGHTWAVE SYSTEMS, IEEE photonics technology letters, 6(8), 1994, pp. 1039-1042
A simple method for optimization of individual amplifier performance p
arameters for multiple wavelength operation is presented. The method d
etermines the erbium fiber length required to achieve a maximum gain s
ubject to the constraint of minimum spectral gain variations. This sim
plifies the practical implementation of gain equalizers required to ac
hieve flat gain for multiple wavelength operation.
