Abstract (en)
[origin: DE19637396A1] This invention concerns a device for coupling waves guides and optical components, in which the core layers (30, 40) of two optical wave guides (3, 4) are oriented parallel and at a distance (d34) from one another and overlap one another in an overlap area (6). In the overlap area (6), at least one of the wave guides has a reduction in cross section (9). This effects that a wave directed in one wave guide completely transfers into the other in the overlapping area.
