Ionizing radiation (light ions up to 200 keV and UV radiation with λ < 280 nm) is used to structure the surfaces of transparent polymers like Poly-(methyl-methacrylate) and related materials. Areas with an index increase up to 1% suitable for waveguiding are obtained. Compaction of the irradiated areas leads to diffractive structures. Changes in the chemical structures of the irradiated samples are reported. The physical properties like mode spectra and attenuation were measured. Passive components with fibers coupled to the devices were fabricated.
