The characterization of monomode passive polymer optical devices fabricated according to the POPCORN technol. by methods originated from electron, ion and optical spectroscopy is summarized. Impacts of observed waveguide perturbations on the optical characteristics of the waveguide are evaluated. In the POPCORN approach optical components for telecommunication applications are fabricated by photo-curing of liquid halogenated (meth)acrylates which were applied on molded thermoplastic substrates. For tuning of waveguide material refractive indexes with respect to the substrate refractive index frequently comonomer mixtures are used. The polymerization characteristics, especially the polymerization kinetics of individual monomers, determine the formation of copolymers. Therefore the unsaturation as function of UV-illumination time in the formation of halogenated homo- and copolymers was examined From different suitable copolymer system, after characterization of their glass transition temperatures, their curing behavior and their refractive indexes as function of the monomer ratios, monomode waveguides applying PMMA substrates were fabricated. To examine the materials composition also in the 6 X 6 μm2 waveguides they were visualized by TEM. With this method, e.g., segregation phenomena could be observed in the waveguide cross section characterization as well. The optical losses in monomode waveguides caused by segregation and other materials induce defects like micro bubbles formed as a result of shrinkage were quantized by return loss measurements. Defects causing scattering could be observed by confocal laser scanning microscopy and by conventional light microscopy.
