Modeling of highly multimodal optical interconnects for time domain analysis

The integration of optical interconnects into electronic systems results in hybrid electrical-optical interconnects. To design such systems the physical behaviour of the electrical and optical parts has to be modeled. The latter one requires the consideration of the technological given facts typical for the addressed interconnection level (component-, module-, and system-level) in order to select appropriate numerical methods and simulation models. In case of guided wave optics the interconnection level characteristic dimensions determine whether the optical single-mode or multimode technology is applicable. An approach is described which enables the application of recursive convolution algorithms leading to very accurate results.
