Abstract:
1. An electrically pumped tuneable laser source comprising: a first optical confinement layer extending along an Oxy reference plane and forming a distributed Bragg reflector for a pump wave at a pump wavelength; an active layer made of non-linear semiconducting material extending on the first optical confinement layer, the average refraction index of the active layer being greater than the average refraction index of the first optical confinement layer; a second optical confinement layer extending on the active layer, the average refraction index of the second optical confinement layer being less than the average refraction index of the active layer; a base with a first width along an Ox axis; a ribbon extending on the base, said ribbon having a second width along the Ox axis less than said first width, the second width being less than 10 μm; wherein the active layer comprises at least one plane of quantum boxes capable of emitting a pump wave at a pump wavelength; wherein the ribbon comprises: said ribbon enabling emission, by parametric conversion from the pump wave, of a signal wave and a complementary wave, the second width being selected to match a phase between the pump wave, the signal wave and the complementary wave.
