Abstract
An optical amplifier of the type including an inlet for a light signal to be amplified and an outlet for an amplified light signal that has been amplified by means of an amplifying waveguide that is controlled by regulation light coming from a pumping diode; the amplifier comprising: an optical circulator having an inlet port receiving the light signal to be amplified, an outlet port delivering the amplified light signal, and two intermediate ports, the first of the intermediate ports being connected to the amplifying waveguide; and regulation means having an inlet connected to the second of the intermediate ports and an outlet connected to the pumping diode, whereby the amplifying waveguide has equalized gain for all of the carrier waves constituting the amplified light signal.
