1. A device for coupling an optical fiber with a nanophotonic component formed on a first support, the device comprising:

  • an intermediary component formed on a second support, comprising a first waveguide capable of receiving the light from the optical fiber and transmitting it to a first diffraction grating whatever the polarization of the incident light;

    second and third diffraction gratings formed on the first support and coupled to the nanophotonic component,the first diffraction grating being capable of delivering first and second light beams towards, respectively, the second diffraction grating and the third diffraction grating, the first and second beams having perpendicular polarizations.
