<p>The laser includes an amplifier with III-V heterostructure, designed to generate an optical wave, and a waveguide coupled optically to the amplifier, said waveguide having a hat-shaped cross section, the top of which is proximal to the amplifier. The top of the hat and the lateral sides of the hat are covered with a layer of a dielectric material in the vicinity of the amplifier. The hat is formed by a base and a protrusion of the waveguide, the material forming the base being distinct from the material forming the protrusion.</p> |
