    Abstract: A distributor for optical signals characterized by a waveguide structure disposed on the substrate. The waveguide structure has an input and a plurality of output ends with a tree-like branching structure having at least one branching point with two curved branching sections extending therefrom. Each of the curved branching sections has a radius of curvature great enough so that the guiding of optical signals in the branching section is not impaired.

    Abstract: A method of producing a light conductor structure having a pair of light conductors embedded in a substrate and electrodes arranged between the light conductors which structure is particularly adapted to be used as an electrically controllable coupler, characterized by providing a substrate, applying a strip of diffusion material on the substrate at the location of each of the light conductors, covering each of the strips of diffusion material with a protective layer of material, applying a metal layer to the substrate and the layer of protective material, removing the protective layer and the metal layer supported thereon, and then diffusing the diffusion material into the substrate by heating to a desired temperature. The embodiments of the method include applying an adhesive layer prior to applying the metal layer to facilitate the attachment of the metal layer on the substrate and applying a dielectric layer prior to applying either the metal layer or the adhesive layer to prevent diffusion of either the adhesive or metal layer into the substrate during the diffusion process.

    Abstract: Planar single-mode optical waveguides which can conduct light with defined polarisation have so far been embedded in, for example, a cladding made from crystalline LiNbO.sub.3. The crystalline structure of the cladding produces disadvantageous properties such as the fact that the birefringence depends on the geometric profile of the guide, relatively high optical loss, poor fibre coupling, birefringence rigidly fixed by material constants, and a costly manufacturing process. The new process results in an optical waveguide in which both the cladding and the actual guide itself are made of glass with a certain composition, thereby avoiding the disadvantages stated. With the help of a non-isothermal plasma CVD process a light-guiding core region (1) is surrounded on a substrate (4) by cladding layers (2, 2') and a cladding region (3, 3'), the thermal coefficient of longitudinal expansion of the cladding region (3, 3') differing markedly from that of the two homogeneous cladding layers (2, 2'). The core region has either a higher or approximately the same refractive index as the cladding region. Use of the optical waveguide is as a polarisation-receiving or polarising single-mode optical waveguide.

    Abstract: A device for forming a connection between a first and second group of glass fibers with each fiber of the first group being held in alignment with a given fiber of the second group characterized by an elongated carrier member having longitudinally extending grooves and a shrinkable tube telescopically received on the elongated member. In forming the connection, the glass fibers of one group are inserted individually in separate grooves from one end of the carrier member and the fibers of the second group are inserted from an opposite end until their end faces abut and engage the end faces of the respective fiber of the first group. After insertion, the tube is shrunk such as by a heat shrinking step so that the fibers are tightly and firmly held in their respective grooves by the shrinkable tube.

    Abstract: An output/input coupler for multi-mode glass fibers characterized by a substrate and a main line having a square cross section disposed on the substrate and having at least one branch line extending on said substrate therefrom with the branch line having a rectangular cross section smaller than the cross section of the main line and having one surface coplanar with the surface of the main line. The branch line may have the same thickness as the main line with a reduced width or may have both a reduced thickness and width. In one embodiment, the branch line extends as an arc and may terminate in an end line which has a square cross section equal to the cross section of the main line and extends at an angle to the main line. In another embodiment, the branch line extends rectilinearly and may terminate in an end line which extends parallel to the main line and has a square cross section equal to the square cross section of the main line. The coupler may be formed by stamping the coupler from a sheet of material or by using a photolithographic process to form the coupler from a layer of photosensitive material. If the coupler has branch lines with a thickness less than the thickness of the main line, the photolithographic process includes developing a first layer or foil of photosensitive material to form part of the main line and the branch line and then developing a second applied layer to produce the remaining portion of the main line.

    Abstract: A method for the manufacture of a light wave guide providing a cladding and a light conducting core, from a glass tube, showing a material on or below its inner surface which forms the core of the finished light wave guide comprising at least one substance which is diffused out selectively of this material, forming the core subsequently, into the interior space of the glass tube, whereby during the diffusing-out process the partial pressure of the diffusing-out substance in the interior space of the glass tube is maintained as small as possible, whereby a premature collapsing of the glass tube during the diffusion process is prevented by adjusting an overpressure in the glass tube, that the glass tube after the diffusing out process is largely collapsed by rinsing with a rinsing gas and in a last collapsing step is completely collapsed to a rod (perform) without rinsing with a rinsing gas and that the rod is subsequently drawn out to a fiber.
