Claim 0:
1. A laser source, comprising:
a functionalized substrate, comprising an integrated waveguide, said integrated waveguide:
being formed from a stack of a first portion and of a second portion, an upper face of the first portion being at least partially coated with the second portion, and
comprising at least one Bragg grating; and

a semiconductor pad, resting on the functionalized substrate, comprising a gain medium located in an active waveguide, the active waveguide being located perpendicular to the integrated waveguide and oriented parallel thereto, the two waveguides being optically coupled to each other, wherein
the Bragg grating is located in the upper face of the first portion,
the Bragg grating is covered by the second portion,
the second portion does not comprise a Bragg grating, and
the second portion forms a longitudinal rib of a width smaller than that of the first portion.
