Abstract

La présente invention concerne un émetteur optique à distorsion réduite. Un émetteur optique selon la présente invention utilise deux trajets d'entrée. Le signal d'entrée Sin est divisé en des signaux S1 et S2 . Le signal S 1 passe par un premier photo-émetteur 12 et un premier photo-récepteur 13. Le deuxième signal d'entrée S2 passe par un circuit de retard 16. La différence entre le signal de sortie du récepteur 14 et le signal de sortie du circuit de retard 16, effectuée par un sommateur 15, est fournie à un émetteur optique 18 de mêmes caractéristiques que l'émetteur 12. Application aux télécommunications optiques.
