Abstract[English]
A laser (10)comprising a photonic component (14) comprising a gain medium; and a waveguide platform (12) comprising a Distributed Bragg Reflector, DBR, section (18). The photonic component is optically coupled to the waveguide platform. One or more thermal heaters (28) are positioned at the DBR section (18) of the waveguide platform, and/or at a phase section (16) of the waveguide platform located between the gain medium and the DBR section.[French]
L'invention concerne un laser comprenant un composant photonique comportant un milieu de gain ; et une plate-forme guide d'ondes comprenant une section de réflecteur de Bragg distribué, DBR. Le composant photonique est couplé optiquement à la plate-forme guide d'ondes. Un ou plusieurs réchauffeurs thermiques sont positionnés au niveau de la section DBR de la plate-forme guide d'ondes et/ou au niveau d'une section de phase de la plate-forme guide d'ondes située entre le milieu de gain et la section DBR.
