Abstract

L'invention a pour objet une diode laser à résonateur distribué. La couche active de cette diode a une bande de conduction ou au moins des niveaux d'énergie plus bas que celles des couches épitaxiées dont elle est formée, et que celle de son substrat. Celui-ci est donc transparent à la longueur d'onde de la lumière émise. L'invention s'applique aux télécommunications optiques.The subject of the invention is a laser diode with a distributed resonator. The active layer of this diode has a conduction band or at least energy levels lower than those of the epitaxial layers from which it is formed, and than that of its substrate. This is therefore transparent to the wavelength of the light emitted. The invention applies to optical telecommunications.
