As a production engineering institute, we at the ITA are researching innovative manufacturing processes for optical fibers in order to integrate optical transmission paths into conventional circuits. The Mosquito method, for example, enables the integration of optical fibers on 3D mechatronic devices through high-precision wet-on-wet dispensing on a system with 6DoF. We are also investigating unconventional methods such as flexographic and gravure printing for their potential applications in waveguide technology. Compared to conventional methods, these processes represent a cost-effective and high-throughput alternative. The polymer optical waveguides produced can be integrated into multilayer PCBs. To optimize the waveguide networks, we work on neural transformer networks that use deep learning methods, among other things.

Our research group also deals with the assembly and connection technology of integrated optical systems. Various devices are available for different research projects and applications, which enable discrete component assembly and integration through to complete mechanical, electrical and optical contacting. This includes, for example, a fine placer with integrated adhesive application as well as various soldering systems and wire bonding systems for electrical contacting. With the help of this equipment, precise and reliable work in the field of optical system integration is possible.

Another field of research is the production of optics under microgravity. The Einstein elevator enables us to extend the parameter space of manufacturing processes to include gravity and oxygen content, thus opening up new relationships and possibilities for optical components. Recently, we investigated the production of lenses under conditions similar to those in space.
