The invention relates to planar integrated coupling circuits. A planar integrated optical circuit comprises at least a first planar duplex combining/branching circuit (1) which comprises a first planar inlet/outlet (109, 110) being connected to a first optical fiber circuit (A) and a second planar inlet/outlet (111, 112) which is connected to a second optical fiber circuit (B) and in case of an extension of the planar integrated circuit a third planar inlet/outlet (113, 114) is connected to a first outlet/inlet (210, 209) of a second planar duplex combining/branching circuit (2) of identical interconnection as the first planar duplex combining/branching circuit (1). In case of a further extension of the integrated circuit a third inlet/outlet 213, 214 of the second planar duplex combining/branching circuit (2) is connected to a first outlet/inlet of a following planar duplex combining/branching circuit (N). This planar integrated circuit can be used for communication and telecommunication networks of any multipoint configuration for a quick optical communication of processors and of systems, the basis of which is a combining and branching of optical duplex and semiduplex communications. |
