Abstract
The invention relates to a device for coupling an optical fiber and a nanophotonic component formed on a first substrate, wherein the device comprises: an intermediate component formed on a second substrate including a first wave guide adapted for receiving light from the optical fiber and for transmitting the same to a first diffraction grating independently from the polarization of the incident light; second and third diffraction gratings formed on the first substrate and coupled to the nanophotonic component, the first diffraction grating being adapted to provide the first and second light beams respectively towards the second diffraction grating and the third diffraction grating, the first and second beams having perpendicular polarizations.
