Claim 7:
8. A process for fabricating a laser source according to claim 1, comprising the following steps:
producing a first portion of the integrated waveguide resting on a base layer;
producing at least one Bragg grating in the upper face of the first portion opposite the base layer, the Bragg grating being formed from an alternation of teeth and troughs;
filling the troughs with a material of low refractive index;
producing a second portion of the integrated waveguide on the first portion and covering the Bragg grating;
producing an upper layer covering the second portion; and
producing the semiconductor pad resting on the upper layer.
