ABSTRACT:
A branching element for distributing light from a group of incoming waveguides to outgoing waveguide groups characterized by a member having at least three separate groups of channels, all the channels in each group being parallel to each other and lying in a plane of the group, two of said groups of channels being aligned to lie in the same plane with the channels of the one group being axially aligned with the channels of the other group and separated therefrom by a common partially permeable reflecting layer extending at an angle to the plane and formed by the two groups of channels, at least one additional group of channels extending at an angle to the plane of the two aligned groups of channels and intersecting the aligned two groups of channels at a common reflective layer, and light waveguides being arranged in each of the channels, the light waveguides in the channels of the two aligned groups having end faces extending in the plane of the layer and enaged therewith and the waveguides in the additional groups having end faces engaging the waveguides in one of the two aligned groups of channels.
