摘要

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 μm; 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.

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:
the part of the active layer comprising the quantum boxes plane;the second optical confinement layer; 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 the phase between the pump wave, the signal wave and the complementary wave.
