Technologies for robust optical coupling of integrated waveguides during field assembly inextended structures

组件集成光网络结构的应用有可能在未来消除复杂的电缆组件。目前，由于缺乏可靠的现场装配技术，限制了大型结构件的广泛应用。在这里，一个强大的光学耦合接口提出了特别的挑战。这个子项目的目的是为这个耦合问题的概念和技术的发展。该研究项目的主要目标是研究具有集成光学功能的三维设备（opto 3D-MID）与光机电一体化组件上的光学总线网络结构之间的光学互连，这使得现场的组装过程更加强大。为了优化和加速所研究的光学耦合元件的实施，设计过程将由光学模拟来支持。在项目的第一阶段，光学无源-无源耦合器将使用紫外光刻在柔性衬底上实现。这一专门知识将在第二阶段转让，以便在使用气溶胶喷射印刷制造的波导上实施光学耦合。

The application of component integrated optical network structures has the potential to eliminate complex cable assemblies in the future. So far, the lack of robust field assembly technologies prohibited the wide application on large structural elements. Here, a robust optical coupling interface poses the particular challenge. This subproject aims at the development of concepts and technologies for this coupling issue. The main objective of the research project is the investigation of optical interconnection between the three-dimensional devices with integrated optical function (opto 3D-MID) and the optical bus network structure on an opto-mechatronic component, which enables a robust assembly process in the field. In order to optimize and accelerate the implementation of investigated optical coupling element, the design process will be supported by optical simulations. In the first period of the project, the optical passive-passive coupler will be realized on flexible substrates using UV-photolithography. This expertise will be transferred in the second phase for the implementation of optical coupling on waveguides fabricated using aerosol-jet printing.
