Abstract
An optical fiber amplifier with an absorber, including a first amplification unit for amplifying an input signal light, using first pump light; an absorption unit for separating the signal light and the pump light from the output light of the first amplification unit and absorbing a light signal in a wavelength range; and a second amplification unit for amplifying the signal light output by the absorption unit, using second pump light. The optical fiber amplifier can be easily manufactured by adding an absorber, an erbium doped fiber, to a conventional optical fiber amplifier. The characteristics of the optical fiber amplifier can be easily changed by controlling the length of the absorber.
