PhoenixD - Electrical integration of optical networks

Implementing optical precision systems quickly and cost-effectively using additive manufacturing: This is the vision of PhoenixD. Researchers from the fields of mechanical engineering, physics, electrical engineering, computer science and chemistry work together to simulate, manufacture and apply optical systems. Up to now, such systems have mostly been manufactured on a glass-based basis in small steps, often even by hand. Experts from the various disciplines now want to work together on a digitalized manufacturing system so that individualized products can be realized. In this sub-project, research is being conducted into the cost-effective development of concepts for optical systems. A further task in this project is the assembly, handling and contacting of light sources and light sinks.

The simultaneous mechanical fixing and electrical contacting is called bonding. In this process conductive adhesives containing e.g. metal particles are applied to ensure the contacting. The light sources and sinks, which are only a few hundred micrometers wide and long, are picked up with a high-precision tool via a vacuum suction head and placed at the desired location.

The optical coupling of the light sources to the optical waveguide, which is e.g. printed or dispensed, is another research question that needs to be solved. Here, precise mounting and alignment to the end face of the waveguide is of enormous importance.
