Abstract

A routing optical matrix switching method which constitutes of a novel nonblocking routing optical Crossbar network system is presented. The routing optical Crossbar network includes two parts: one is a routing fan-out unit which provides multi-optical channels for each input light beam, and the other is a routing fan-in unit which combines the optical channels with the same destination output port into one. A module of 4×4 routing optical matrix switching module was developed by this method, which is as well applicable to 2×2,8×8, etc. These optical matrix switches can widely be used in the field of DWDM communications.
