ABSTRACT:
A multiple branching means for distributing light from light wave guides for a plurality of horizontally extending light wave guide channels and a plurality of transversely extending light wave channels coupled to said horizontally extending channels and wherein a mirror layer is formed on an angle .phi..gtoreq.45.degree. at the junction point between the horizontal and vertically extending channels with light wave guides mounted in the channels and wherein the mirror layer is designed as an edge variable filter so that the wavelength of the filter is varied from one filter end perpendicular to the light wave guides in the guiding channels as a function of the distance X from said one end.
