A method of compensating for dispersion in an optical communications system, the method comprising the steps of: positioning a semiconductor amplifier between a first and a second length of optical fibre, launching optical signals into the first length of optical fibre, directing optical signals emerging from the first length of optical fibre into the semiconductor optical amplifier, supplying optical pump radiation to the semiconductor optical amplifier so that the optical signals and the pump radiation interact within the semiconductor opdcal amplifier and generate the phase conjugate of the optical signals, snd launching the phase conjugate optical signals into the second length of optical fibre.

On décrit un procédé pour compenser la dispersion dans un système de communication optique, le procédé comprenant les étapes consistant à: placer un amplificateur optique à semi-conducteur entre une première et une seconde longueur de fibre optique; émettre des signaux optiques dans la première longueur de fibre optique; diriger les signaux optiques sortant de la première longueur de fibre optique dans l'amplificateur optique à semi-conducteurs; fournir des radiations de la pompe optique à l'amplificateur optique à semi-conducteur pour que les signaux optiques et les radiations de la pompe interagissent dans l'amplificateur optique à semi-conducteur et génèrent la phase conjuguée des signaux optiques; et émettre les signaux optiques à phase conjuguée dans la seconde longueur de fibre optique.
