Abstract: Method for the production of an optical coupler for polymer light-guides by arranging the light-guides in the same direction and bundling them by means of a plastic shrink-fit sleeve. In this method, two to 10 polymer light-guides are arranged in the same direction and bundled and a plastic tube is slipped over the mixing zone. Subsequently, a piece of plastic shrink-fit sleeve is pushed over the plastic tube and the shrink-fit sleeve is heated to a temperature at which it contracts. The shrinking temperature of the shrink-fit sleeve is within the thermoelastic temperature range of the plastic tube. The light-guide bundles may be stretched during or after heating.

Abstract: HOE 90/F 357 Process for the production of an optical coupler for polymeric optical fibers In a process for the production of an optical coupler for polymeric optical fibers using ultrasound welding, the fibers are warmed, before the welding, to a temperature of from 50 to 250.degree.C for from 0.2 to 3 hours. The polymeric optical fibers are introduced into a plastic tube which melts with the fibers during the welding operation to form a unit. In another embodiment, a connector bar which has the same refractive index as the core material of the polymeric optical fibers can be inserted into the plastic tube, the polymeric optical fibers are brought into contact with the connector, and the plastic tube, the connector bar and the fibers are welded to one another under the action of ultrasound.

Abstract: Process for manufacturing an optical coupler for polymer light-guides with the aid of the ultrasonic welding technique. The fibres (2, 6) are heated to a temperature of 50 to 250 DEG C for 0.2 to 3 hours before welding. The polymer light-guides are introduced into a small plastic tube (5), which during the welding operation fuses with the said light-guides to form a unit. In another embodiment, a mixer rod, which has the same refractive index as the core material of the polymeric optical fibres, can be introduced into the small plastic tube (5), the polymeric optical fibres are brought into contact with it and the small plastic tube, the mixer rod and the fibres are welded to one another under the effect of ultrasound. … …

Abstract: HOE 91/F 21 of the disclosure Process for the production of a planar optical coupler A process for the production of an optical coupler having any selectable geometry from a polymer film, wherein the film is situated on a plate which is stamped into the desired shape by means of a preheated stamping tool with the application of pressure. The process according to the invention permits the production of a large number of couplers within a short period of time, the couplers produced in this manner possessing a very homogeneous mixing region and good optical properties. The couplers produced by the process according to the invention are distinguished by particularly low insertion losses and excess losses.

Abstract: Method of manufacturing optical couplers from polymers, the coupler structure being produced with the aid of an injection-moulding process and amorphous polymers, in particular PMMA, polystyrenes, polycarbonates, polyolefins, polyesters, polysulphones, polyethersulphones, polyetherimides, polyacrylates, polyamides or polyestercarbonates being used with preference as polymers. The coupler element is solid and may be coated with a polymer which has a lower refractive index than the coupler, so that the diversion takes place in the coupler itself.

Abstract: HOE 9O/F 345 Heat-resistant optical moldings, and a process for their production A process for the production of optical moldings from polysilazanes or polyhydridochlorosilazanes in which the polysilazanes or polyhydridochlorosilazanes are pressed to give moldings or dissolved in a solvent and extruded and are subsequently exposed to a gas atmosphere at a temperature in the range from 10 to 200.degree.C and a relative humidity in the range from 20 to 100% for from 0.1 to 24 hours. The moldings have a core/cladding structure, the cladding comprising from 1 to 3% by weight of O, from 20 to 25% by weight of N and from 30 to 40% by weight of Si, and the core comprising 100% by weight of a polysilazane or polyhydridochlorosilazane.

Abstract: HOE 90/F 128 Process for producing an optical coupler for polymer optical waveguides Process for producing an optical coupler for polymer optical waveguides by arranging the optical waveguides in the same sense and bundling them by means of a plastic shrink-on sleeve. In this process, two to 105 polymer optical waveguides are arranged in the same sense and bundled and a plastic tube is put over the mixing region. Then a piece of plastic shrink-on sleeve is pushed over the plastic tube and the shrink-on sleeve is heated to a temperature at which it contracts. The shrinkage temperature of the shrink-on sleeve is inside the thermoelastic temperature range of the plastic tube. The optical waveguide bundle may be stretched during or after heating.
