Multi-stage switching is very suitable for implement- ing interconnection systems operating at different physical scale (from rack-to-rack to on-chip) and with several technologies (either photonics or electronics). Several multistage architectures have been proposed to design these systems in a highly modular and efficient way. Since these proposals are general and appli- cable to a vast range of technologies, optimizations are possible once a specific technology is considered. In this work we aim at optimizing multi-stage banyan and EGS architectures in case of optical waveguide technology implementation. We propose a method to decrease the number of waveguide crossovers, while avoiding an excessive increase of waveguide bends.
