1. A method for introducing light into a waveguide (3) formed on the upper surface of a microelectronics substrate, by means of a distributed feedback laser device formed by the association of an SOI-type structure having a portion forming said waveguide (3), of a stack of III-V semiconductor gain materials (5) partially covering the waveguide (3), and of an optical grating (9), wherein the grating step is selected so that the optical power of the laser beam circulates in a loop from the III-V stack (5) to the waveguide (3).
