Abstract

See full text

An optical waveguide structure has lines (2), crossings (3), and branchings (4). In the area of the branchings (4), the waveguide structure consists of planar waveguides made of a waveguide material that is put into troughs (7) formed into a substrate (8). The waveguide material has a higher refractive index than the material delimiting the troughs (7). In the area of said crossing (3) the waveguide structure consists of fibers (5) which cross in the area of the crossings.
