Abstract
A photonic device comprising: a support; an intermediate layer (; an optical guiding level including a waveguide and a first to a fifth waveguide section. The photonic device further includes a first dielectric layer covering the optical guiding level and a gain structure in contact with the first dielectric layer. The second and fourth waveguide sections and the first and second ends of the gain structure form a first and a second zone of optical transition between a laser hybrid waveguide, and respectively the first and the fifth waveguide sections. A pattern forming a Bragg grating is arranged over a first part of the thickness of the third waveguide section which is away from the gain structure.
