Abstract

A multistage optical nonguided switching network has been proposed with orthogonally polarized data and address information. This network is unique in that the data information remains in optical form throughout the network (i.e., it is never converted into electrical information). Since the data are never regenerated throughout the network, the system has two main characteristics: (1) the bandwidth of the data is not restricted by electrical circuit considerations; and (2) the optical interconnections from one stage of the network to the next must be highly efficient. The second effect is of interest here. An interconnection that is 90% efficient between stages results in approximately a 57% attenuation of the data through a nine stage network (eight routing interconnections). After examining several methods for achieving this efficiency, a novel system layout is introduced.
