International Symposium on Future Optics

A transformation process is taking place in the world of optical technologies, which may find a historical equivalent in the step from analog to digital electronics. The price of computing power is steadily decreasing, which allows replacing complex precision optics systems by electro-optical interfaces with digital back ends. At the same time, digitalization is also changing production technology. Additive manufacturing and industry 4.0 lead to individualized fabrication at low cost.

The Cluster of Excellence PhoenixD (Photonics, Optics, and Engineering - Innovation Across Disciplines) at Leibniz University Hannover is going to combine both developments. PhoenixD aims to shift the focus from optimized fabrication steps towards the desired functionality of each individually fabricated optical device. Extensive inline simulations based on the individual results of the production process so far will be carried out during the production. This allows for flexible strategies to adapt following manufacturing steps in real-time. The integration of precise measurement systems into the production environment will be crucial for the success of this approach.

Optical systems composed of traditional components such as lenses, mirrors etc. become more and more powerful due to current developments in the fields of optoelectronics and laser technologies.

However, what follows are increasing precision requirements of optical components and therefore increasing costs for fabrication and assembly. PhoenixD aims to break this development by massive use of digital technologies. Simulation and computer control at every stage and the development of novel functional materials will lead to novel optical systems in the future. These systems will be optimized and fabricated as one piece and omit costly discrete traditional precision components.

Mass production of individualized highly functional optical systems will have a significant social impact. Optical biosensors can be used as analytic devices for environmental engineering or point-of-care medical diagnostics. Eye glasses can be upgraded by adaptive and active functionality like adaptive focal length and head up displays. Other examples are herbicide free weed suppression using guided laser beams, or automotive high speed wireless communication systems.
