METHOD OF MANUFACTURING LIGHT WAVE GUIDE BRANCHINGS AND MULTI-DEMULTIPLEXERS USING THE PRINCIPLE OF BEAM SPLITTING

摘要

A method for manufacturing light waveguide branch elements and multi/demultiplexer elements, which elements operate in accordance with the beam divider principle by providing a first body having a plurality of parallel extending waveguides adjacent one side thereof, cutting the body at an angle to the waveguides to form two parts, after preparing the cut surfaces of the parts, applying a mirror or filter structure onto one of the polished surfaces and reassembling the parts to form an assembly, and forming an element by subsequently positioning and securing a second body on the assembly with the second body having light waveguides extending to one surface and the end faces of the waveguides of the one surface being adjacent to the mirror or filter structure so that light traveling in the waveguides of the first assembly will be reflected into the waveguides of the second body.
