Abstract: A mode conversion and mode separation branched dielectric waveguide element for light comprising branches having optically different characteristics which are surrounded by a medium or media having different refractive indexes from that of the dielectric material or materials forming the branches. In one embodiment, one of the surrounding media is an electrooptical crystal provided with at least one pair of electrodes near the parting portion of the branches. As a modification, the branches may be connected at the opposite ends thereof to form a by-pass construction.
