Abstract

L'invention concerne une puce à circuit photonique intégré (PIC) qui comprend une série de sources modulées produisant chacune une sortie de signal modulé à une longueur d'onde de voie différente de celle des autres sources modulées et un coupleur de longueurs d'onde sélectif ayant une entrée couplée optiquement afin de recevoir toutes les sorties de signal provenant des sources modulées et afin d'émettre un signal de sortie combiné sur un guide d'onde de sortie de la puce. Les sources modulées, le coupleur et le guide d'onde de sortie sont tous intégrés dans la même puce.
