Abstract: High-performance optical couplers for polymer light guides are obtained if light guides are grouped together by means of a piece of plastic shrink-fit tubing and fused. The shrink-fit tubing is thereby heated above the shrinking temperature. The method is simple and inexpensive.

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.

Abstract: HOE 89/F 179 Method of producing a planar optical coupler Channels in which polymeric optical waveguides can be laid can be milled in surfaces of plastic sheets by means of an excimer laser. The free space between the optical waveguides is filled up with a transparent casting resin. The channels produced by means of the laser are distinguished by high dimensional accuracy and low surface roughness.
