Abstract

A method for introducing light into a waveguide 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, of a stack of III-V semiconductor gain materials partially covering the waveguide, and of an optical grating, wherein the grating step is selected so that the optical power of the laser beam circulates in a loop from the III-V stack to the waveguide.
