Claim Text:
1. A method for aligning optical elements of an optical adaptor according to with waveguides of a photonic chip, the optical adaptor monolithically integrating optical elements and first micro-mechanical features, the latter defining at least a first horizontal reference surface and a first vertical reference surface, wherein the first horizontal reference surface is perpendicular to an optical plane, the latter being perpendicular the optical axis of the optical elements, and the first vertical reference surface is perpendicular to the first horizontal reference surface and parallel to the optical axis, the method comprising: putting in contact the first horizontal reference surface and the first vertical reference surface with corresponding second horizontal surface and second vertical surface of the photonic chip, wherein a first distance between the first horizontal reference surface and a reference point associated with the optical element is equal to a second distance between the second horizontal reference surface and a corresponding reference point associated with the waveguide, and wherein, a third distance between the first vertical reference surface and the reference point is equal to a fourth distance between the second vertical reference surface and the corresponding reference point, and wherein putting in contact comprises: setting the first distance equal to the second distance, and setting the third distance equal to the fourth distance.
