A wavelength converter assembly includes a substrate. An epitaxial structure is formed on the substrate with areas of different optical properties. A laser and a photodetector are formed in the epitaxial structure. The photodetector generates a first electrical signal in response to an optical signal. A conditioning circuit is coupled to the laser and the photodetector. The conditioning circuit receives the first electrical signal and provides a second electrical signal to the laser to modulate its optical output.

La présente invention concerne un ensemble convertisseur de longueurs d'onde pourvu d'un substrat. Une structure épitaxiale est formée sur le substrat présentant des zones à propriétés optiques variées. Un laser et un photodétecteur sont formés dans la structure épitaxiale. Le photodétecteur produit un premier signal électrique en réaction à un signal optique. Un circuit de conditionnement est couplé au laser et au photodétecteur. Ce circuit de conditionnement reçoit le premier signal électrique et fournit un second signal électrique au laser pour moduler sa sortie optique.
