Then according to the cascade of IPS and LPS, the multi-stage rearrangeable nonblocking Omega network was introduced. Moreover, the method of bipartition graph was adopted to ascertain the node state of each stage. At last, a module of the rearrangeable nonblocking Omega network, which was integrated with polarizing beam-splitter,λ/2 wave plate and perfect shuffle Plates, was constructed.
