Abstract
A multi-stage optical cross-connect in which sub-switches within the respective stages are spatially distributed relative to sub-switches of adjacent stages such that each input/output of any given sub-switch is respectively optically coupleable with an output/input of a respective sub-switch of an adjacent stage by direct linear optical propagation or by non-interleaving waveguides, such that simple interconnection between stages is provided. The spatial distribution may be accomplished within a single plane or by layering the sub-switches within a given stage.
