Abstract (technical / expert description):

So far, there is no software for the design as well as for the affiliated optical simulation of spatially structured, optomechatronic assemblies. Within the research group Optaver, this deficit should be eliminated by regarding the production processes of the other subprojects and their design rules for the above mentioned assemblies.The applicant Prof. Franke enhances the program MIDCAD which supports the layout process for spatial electronic assemblies, so called 3-D molded interconnect devices (3D-MID). The first step is to check and, if necessary, to increase the accuracy of the face representation in MIDCAD. In particular, the closure of smallest gaps within the size of waveguides is a requirement for the representation of optomechatronic assemblies. The characteristic designs of the other subprojects will be modeled in MIDCAD. Special attention will be paid to the analysis and description of signal paths und the parameters of production processes. Thus the MID product model can be extended with an optical partial model containing characteristic values of materials, optical variables of signal transmission, efficiency of coupling, process parameters and standard design elements. Within the scope of the research group, bidirectional data transfers to the subprojects 1 to 5 will be established.The applicant Prof. Lindlein has developed over many years the ray optical simulation tool RAYTRACE which allows the simulation of quite arbitrary three-dimensionally structured optical systems. Since most projects of Optaver will fabricate and use highly multimode wave guides ray optics based simulation methods are valid. Hereby, also the temporal behavior of the propagation of a signal has to be treated. Therefore, the dispersion due to the different spatial modes has to be taken into account. Additionally, an approach based on non-sequential ray tracing is necessary since the order of the surfaces of the optical system, which are hit by a ray, depends itself on the spatial mode. During the project it is also planned to identify repeating subsystems in typical 3DMIDs. Then, design strategies can be integrated into MIDCAD without performing a concrete numerical ray optical simulation since the results of such a simulation were determined before and stored in a data base.A further, import goal of this subproject is the data exchange between the software tools MIDCAD and RAYTRACE. This exchange should contain analytical description of faces, calculations of damping, signal run times and impulse answers. The transfer will be manually executed at the beginning, but later on the exchange of files respectively even the integration of the source codes is planned.
