Optical data transmission will play a significant role in future information and communication technologies, because new solutions are needed to handle the growing volume of data and because the trend toward even greater miniaturization and higher scales of integration increases the thermal and electrical load on components. Progress will depend on the availability of materials for single-mode and multimode waveguides that ideally allow loss-free operation by virtue of their intrinsic properties and the quality of the manufacturing process. Fraunhofer ISC develops technologies that permit an optimized spatial resolution of the waveguides and improve the coupling/decoupling processes in optoelectronic components, and are particularly suited for optical interconnects at board, module and chip level. The two-photon absorption polymerization process being developed by Fraunhofer ISC for this purpose enables three-dimensional optical waveguides to be manufactured without wasting energy or resources, and is compatible with existing assembly processes.
