Abstract: The invention relates to a light source comprising a photonic wire having a single-mode core and adapted to support an optical mode which is degenerate in polarization, comprising an emitter of a pair of photons which are intended to be entangled in polarization. The photonic wire comprises a cladding which is asymmetrical in rotation and extends along a principal transverse axis. Furthermore, the light source comprises a correction device adapted to induce by electrostatic effect a mechanical deformation of the photonic wire in a plane parallel to the substrate, along a deformation axis forming an angle of inclination of between 0° and 90°, these values being exclusive, with respect to the principal transverse axis, the mechanical deformation leading to mechanical strains experienced by the emitter, thus improving the degree of entanglement of the photon pair.
