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光缆组件。到目前为止，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，坚固的光耦合接口构成了特别的挑战。这个子项目旨在为这一耦合问题开发概念和技术。该研究项目的主要目标是研究具有集成光学功能的三维器件(OPTO 3D-MID)与光机电组件上的光总线网络结构之间的光学互连，从而实现现场可靠的组装工艺。为了优化和加速所研究的光耦合元件的实现，设计过程将得到光学仿真的支持。在该项目的第一阶段，将利用紫外光刻技术在柔性衬底上实现光学无源-无源耦合器。这项专门知识将在第二阶段转让，以便在使用气雾剂喷墨打印制造的光波导上实现光耦合。

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.
