The invention comprises (a) a divider (D) by 2 of the optical power received at one input (E1, E2) and (b) two groups of single mode waveguides coplanar to the divider and symmetrical relative to the axis of symmetry (Z) of the divider (D), each group being composed of waveguide sections connected in tree and branch fashion by Y junctions (Jii) between one input junction (J11, J12) connected to one of the outputs of the divider and N sections of waveguide difining N outputs (S1 to S16) of the coupler parallel to the axis of the divider. According to the invention, each of these input junctions (J11, J12) has a rectilinear input branch (B1) with predetermined length such that the transverse distribution of the optical power at the output of the rectilinear input branch (B1) is centered to a large degree on the axis of this input branch.
