FOR 1660: Optical Design and Interconnection Technology for Assembly-Integrated Bus Systems

根据课题组开始时的计划，在第二个资助期将研究光总线系统从平面设计到三维设计的过渡，以进一步提高集成密度，扩大技术产品的设计自由度。由此产生的三维光机电一体化器件（3D-Opto-MID）实现了机械，电气和光学功能的结合，并解决了汽车，航空和工业4.0领域的广泛应用。第二个资助期的目标是实现带宽超过10gbit / s（对应400个并行4K视频信号）的三维传输线。在第一个资助期的结果的基础上，将在未来三年内研究三维条件基板上波导的建模、仿真、增材生产和柔性耦合的解决方案。从这项任务中产生了新的科学问题，就像在第一个资助期一样，通过跨地点的专业知识交流来解决这些问题：TP 1.2：如何可能(i)通过印刷技术和（ii）光束处理技术来调节平面聚合物基板，同时考虑和补偿局部扭曲，从而提供光学功能化箔在三维物体上的应用？TP 2.2：如何在空间曲面上通过增材制造生产高质量的聚合物光波导？TP 3.2：如何将具有光学功能的打印聚合物波导通过不对称光总线耦合连接到三维表面，以实现考虑曲面的鲁棒耦合结果？TP 6.2：考虑到制造相关的边界条件，如何在空间对象上(i)建模和（ii）模拟聚合物光波导的几何、功能和光学特性？

As already planned at the beginning of the research group, the transition from a planar to a three-dimensional design of the optical bus system is to be investigated in the second funding period in order to increase the integration density even further and expand the design freedom of technical products. The resulting three-dimensional opto-mechatronic integrated devices (3D-Opto-MID) enable a combined mechanical, electrical and optical functionality and address a wide range of applications in the fields of automotive, aviation and industry 4.0. The goal of the second funding period is the realization of a three-dimensional transmission line with a bandwidth of more than 10 GBit / s (corresponds to 400 parallel 4K video signals). On the basis of the results of the first funding period, solutions for modeling, simulation, additive production and flexible coupling of waveguides on conditioned substrates in 3D are to be investigated over the next three years. From this task new scientific questions arise which, like in the first funding period, are adressed with exchange of expertise across locations:TP 1.2: How is it possible to condition a planar polymer substrate (i) by means of printing technology and (ii) beam processing technology while considering and compensating local distortions in such a way that applications of the optically functionalized foil on three-dimensional objects is provided?TP 2.2: How is it possible to generate high quality polymer optical waveguides by means of additive manufacturing on spatially curved surfaces?TP 3.2: How can printed polymer waveguides with optical functionalities be connected to three-dimensional surfaces by means of asymmetrical optical bus coupling, in order to achieve robust coupling results considering curved surfaces?TP 6.2: How can the geometric, functional and optical properties of polymer optical waveguides be (i) modeled and (ii) simulated on spatial objects, taking into account the manufacturing-related boundary conditions?
