Next generation high-speed pc board interconnects will be based on integrated optical multimode waveguides with cross- sectional sizes comparable to those of electrical microstrip lines. The design of such interconnects requires appropriate simulation models of the multimode waveguides and the laser- and photo-diodes, as well. Since single-mode interconnects can be modeled very efficiently by well known numerical methods such as FEM and BPM, these methods are not applicable for optical multimode waveguides with more than 1000 propagating modes. Due to the numerical complexity only methods based on geometrical optics, called ray tracing, can be applied efficiently. This paper deals with a time domain modeling and simulation approach for analyzing the signal behavior of multimode waveguide based electrical-optical interconnection systems as a whole. Modeling of multimode waveguide components as well as macromodeling of laser- and photo-diodes is explained in detail. The modeling approaches are discussed by examples.
