HOE 90/F 095 - 4 - ABSTRACT OF THE DISCLOSURE Process for the production of optical couplers from polymers A process for the production of optical couplers from polymers in which the coupler structure is produced by injection molding and the polymers employed are prefer- ably amorphous polymers, in particular PMMA, polysty- renes, polycarbonates, polyolefins, polyesters, polysul- fones, polyether sulfones, polyether imides, polyaryl- ates, polyamides or polyester carbonates. The coupler element is solid and may be coated with a polymer which has a lower refractive index than the coupler, so that the light propagation takes place in the coupler itself.
