Abstract

The invention relates to a device for coupling a flared laser source (10) and an output waveguide (3), comprising a coupler (20), a combiner (40), and a network of intermediate waveguides (30) located between the coupler and the combiner and comprising a correcting central section (Sc) in which an effective index associated with the guided modes is adjusted so that the optical paths of the intermediate waveguides (30) between the coupler (20) and the combiner (40) are identical to one another.
