Abstract (technical / expert description):

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 (FOR 1660/0) 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.
