Plane-to-plane guided-wave-based interconnection modules are proposed as building blocks for scalable optoelectronic multistage interconnection networks (MINs). This approach leads naturally to a MIN paradigm based not on cascading switching stages containing several size-reduced crossbars, as in the shuffle-exchange networks, but on cascading permutationreduced crossbars instead, one per stage. The interest of such an architecture lies in the control simplicity and scalability potential.

Preliminary experiments using fiber-based interconnection modules are presented. Performance analysis and simulation of a buffered GSMIN is also studied for packet routing purposes.
