Abstract:
The invention relates to a III-V heterostructure laser device ( 1 ) arranged in and/or on silicon, comprising: a III-V heterostructure gain medium ( 3 ); and an optical rib waveguide ( 11 ), arranged facing the gain medium ( 3 ) and comprising a slab waveguide ( 15 ) equipped with a longitudinal rib ( 17 ), the optical rib waveguide ( 11 ) being arranged in the silicon.   The optical rib waveguide ( 11 ) is oriented so that at least one Bragg grating ( 19, 19 a,  19 b ) is arranged on that side ( 21 ) of the slab waveguide ( 15 ) which is proximal relative to the gain medium ( 3 ) and in that the rib ( 17 ) is placed on that side ( 23 ) of the slab waveguide ( 15 ) that is distal relative to the gain medium ( 3 ).

Claim (Index 1):
A III-V heterostructure laser device arranged in and/or on a silicon substrate, comprising:\n a III-V heterostructure gain medium being integrated on the silicon substrate; and an optical rib waveguide, arranged facing the gain medium and comprising a slab waveguide equipped with a longitudinal rib, the optical rib waveguide being arranged in the silicon substrate; wherein the optical rib waveguide is oriented so that a Bragg grating is arranged on a side of the slab waveguide and is directly beneath and facing the III-V heterostructure gain medium and which is proximal relative to the gain medium without being arranged on a side of the slab waveguide that is distal relative to the gain medium, and in that the longitudinal rib is placed on the side of the slab waveguide that is distal relative to the gain medium.
