Abstract
An assembly including a first waveguide produced in a first photonic chip and that extends in a first direction in order to guide an optical signal at a wavelength λ, an array of a plurality of second waveguides, which is produced in a second photonic chip adjoined to the first photonic chip, and a power summer including inputs that are optically connected to one end of each of the second waveguides. Each of the second waveguides includes upstream and downstream segments that are offset with respect to each other in the second direction. The configurations of the first waveguide and of the second waveguides are such that, for any position of the first waveguide above the array, the distance between one of the segments of the first waveguide and one of the segments of one of the second waveguides is smaller than λ/2.
