A method and passive device for the coherent combination of two amplified and/or spectrally broadened optical beams using at least one bidirectional optical component (A1, A2), the device includes an amplitude division ring interferometer having optical splitting and recombining elements disposed so as to receive an incident optical beam (S0) and to split it spatially into a first secondary input beam (H1) and a second secondary input beam (H2), optical guiding elements disposed so as to define an optical path in the form of a ring in the interferometer, the at least one bidirectional optical component being disposed on the optical path of the ring interferometer, the splitting and recombining elements being disposed in such a way as to receive and to recombine spatially, temporally and coherently the first secondary output beam (H1″) and the second secondary output beam (H2″), so as to form a coherent output beam.
