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 2):
The laser device according to  claim 1 , wherein the Bragg grating comprises a quarter-wave plate in order to ensure a single-mode operation.
