Abstract
An optical amplifier (), and a related optical amplification method, comprising an optical path () having an input end () and an output end (), a first erbium doped optical fiber () placed along the optical path, a first gain flatting filter () placed along the optical path downstream the first erbium doped optical fiber, a second erbium doped optical fiber () placed along the optical path downstream the first gain flatting filter, a second gain flatting filter () placed along the optical path downstream the second erbium doped optical fiber, a third erbium doped optical fiber () placed along the optical path downstream the second gain flatting filter, and an optical pump () optically coupled to the optical path so as to optically pump at least the first and the third erbium doped optical fiber.
