  • On-chip electrically pumped optical parametric source
    Patent number: 9025630
    Abstract: A tuneable laser source includes a first confinement layer forming a Bragg reflector for a pump wave; an active layer made of non-linear semiconducting material, the refraction index of the active layer being greater than the refraction index of the first confinement layer; a second confinement layer, the refraction index of the second confinement layer being less than the refraction index of the active layer; a base with a first width; and a ribbon with a second width less than the first width. The second width is less than 10 ?m; the active layer includes at least one plane of quantum boxes capable of emitting a pump wave and the ribbon includes at least the part of the active layer including the quantum boxes plane and the second confinement layer.
