ABSTRACT:
An optical branching element has an input waveguide (10) and a plurality of output waveguides (20a, 20b), which are so disposed at a distance from the input waveguide (10) that a beam of light launched into the input waveguide (10) over a coupling path of a predefined length couples over with a defined intensity into the output waveguides (20a, 20b).
