Modeling and simulation of optical components on opto-mechatronic assemblies for the representation of characteristic parameters

为了获得印刷聚合物光波导（pow）生产的整个过程链的完整表示，有必要创建这些过程链的虚拟表示，以确定波导和光机电组件耦合结构设计过程中的光学特性。通过研究小组OPTAVER开发的设计策略，几何和光学参数都可以确定并直接传递到生产设施。因此，必须关注计算机辅助建模与仿真。在第一个供资期间进行的一揽子工作就是为此目的服务的。通过将方法扩展到3d - opto - mid和三维波导路径/波导（与印刷pow相关）以及耦合器结构的模拟，可以描述完整的虚拟表示。此外，通过快速波光传播方法扩展了仿真，可以精确地模拟耦合器的结构，并可以定义CAD系统中可用的参数。申请人Franke教授设计了内部软件解决方案MIDCAD，支持空间模制互连器件（3d - mid）的布局。由于MIDCAD和光学模拟系统RAYTRACE之间开发的数据接口，可以确保几何模型和由此产生的衰减值的交换，即产生波导的粗糙度和波纹。通过扩展产品模型（考虑到生产过程的参数），可以用波导的物理、几何、化学和光学特性进行建模，并可以以现实的方式表示它们的行为（3D-Opto-MID）。申请人Lindlein教授开发了射线光学模拟工具RAYTRACE，可以模拟任意排列的三维光学系统。此外，该软件（作为扩展）有一个波光学模拟工具（WaveSim）。通过波光学方法扩展（基于建模的）印刷波导仿真也可以研究射线光学仿真不充分的情况。这方面的例子是波导的缩小尺寸或两个波导的耦合。在研究组的框架内，为子项目1.2至3.2的工作建立了双向数据传输。

In order to obtain a complete representation of the entire process chain for the production of printed Polymer Optical Waveguides (POWs), it is necessary to create a virtual representation of these to determine the optical properties in the design process of the waveguides and coupling structures on opto-mechatronic assemblies. With the design strategy developed by the research group OPTAVER both, the geometrical and optical parameters, can be determined and transferred directly to the production facilities. Thereby, the computer-aided modeling and simulation have to be concerned. The work packages carried out during the first funding period serve this purpose. By expanding the approach to 3D-Opto-MIDs and the simulation of three-dimensional waveguide paths/waveguides (related to printed POWs) as well as coupler structures, a complete virtual representation can be described. In addition, expanding the simulation by a fast wave-optical propagation method, the coupler structures can be precisely simulated and parameters can be defined that are available in the CAD system. The applicant Prof. Franke designed the in-house software solution MIDCAD, which supports the layout of spatial Molded Interconnect Devices (3D-MIDs). Due to the developed data interfaces between MIDCAD and the optical simulation system RAYTRACE, it is possible to ensure an exchange of geometry models and the resulting attenuation values, i.a. resulting out of the roughness and the waviness of the waveguides. By expanding the product models (in consideration of the parameters of the production process), the waveguides can be modeled with their physical, geometric, chemical, and optical properties and can be represented in their behavior in a realistic manner (3D-Opto-MID). The applicant Prof. Lindlein has developed the ray-optical simulation tool RAYTRACE that allows the simulation of arbitrarily arranged three-dimensional optical systems. In addition, the software has (as an extension) a wave-optical simulation tool (WaveSim). The extension of the (modeling-based) simulation of printed waveguides by a wave-optical method can also investigate cases where a ray-optical simulation is not sufficient. Examples for this are reduced dimensions of the waveguide or the coupling of two waveguides. Within the framework of the research group, bi-directional data transfers are set up for the work of the subprojects 1.2 to 3.2.
