A device, utilized for the separation or combination of two signals of different wavelengths, of the type in which the waveguides comprise straight interaction segments (11, 21 ; 11n, 21n) parallel and close to one another and to curved approach segments with inflection points (12, 22, 13, 23; 12n, 22n, 13n, 23n), connected to the ends of the straight segments, and, for certain ones, to inputs/outputs (4,5,6) of the device. In accordance with the invention, the approach segments situated on at least the same side of the straight segments are free of any inflection point, the coupling of the straight segments being optionally modified to compensate for the variation of the coupling between the waveguides along said approach segments due to the omission of the inflection points.
