ABSTRACT:
A multi/demultiplexer is disclosed wherein the light-conducting fibers are cemented into a perforated plate made of a photolithographically etchable material, and their terminal faces are ground down and polished together with the surface of the perforated plate. To compensate for focusing differences, a plate of appropriately matched thickness is disposed between the transparent supporting block and the surface of the perforated plate.
