Abstract
A pulsed laser device including: a III-V-on-silicon type hybrid pulsed laser source, including a gain section and a saturable absorber section which rest on a photonic substrate, and a longitudinal waveguide located in the photonic substrate; a control optical device including an optical pulse emitter source and a lateral waveguide located in the photonic substrate; the waveguides being sized so that the confinement factor Γ, Γin the quantum wells of the corresponding section of the optical mode of the lateral waveguide is higher than the confinement factor I, in the quantum wells of the semiconductor medium, of the optical mode of the longitudinal waveguide.
