This invention relates to the production of integrated optical waveguides on the surface of planar polymer substrates (polymer chips) using UV laser lithography. The resulting optical waveguides are multilayer optical waveguides that, when light is guided in the lower part of the optical waveguide, form radiation modes. As a result, light energy is radiated from the underside of the optical waveguide into the volume of the polymer substrate, so that it is lost to the actual light guide.Since the associated attenuation losses are usually undesirable, two different partial solutions are presented, which can then be combined to suppress the unwanted radiation modes as completely as possible. A parameter window for the UV laser lithographic production of polymeric, integrated-optical (planar) optical waveguides is presented, which is located shortly before the UV photon-induced carbonization (discoloration) of the irradiated zone of the optical waveguides to be produced. Due to the thermal effect of the incident high-energy UV excimer laser radiation, a change in the refractive index depth profile within the irradiated zone occurs above a certain radiation dose, so that no more radiation modes can form there.As a further solution, polyacrylate layers are produced by spin-coating and subsequently curing acrylate layers on a carrier substrate. These layers are too thin for radiation modes to form on the underside of the optical waveguides produced by subsequent UV exposure.
