Abstract

Omega space division architectures for photonic switching are investigated, with focus on optical crosstalk reduction and conflict avoidance. In such networks, many admissible permutations are not crosstalk free, due to the fact that different conflict-free paths are forced to share the same switching elements. To reduce those conflicts, a method operating in a multi-layer structure is proposed, that is based on a bipartite and two-colorable graph algorithm.
