摘　　要：提出了一种新型的基于偏振的光矩阵开关方法 ,通过控制光的偏振态实现严格无阻塞连接。以 4× 4光矩阵开关为例 ,详细给出了其节点开关和交换网络的实现方案。并对该 4× 4光矩阵开关进行实测 ,证明该方法制作的小规模光矩阵开关具有插损低 ,串话小 ,开关时间中等 ,性能稳定 ,工艺成熟等特点。A novel method to fabricate optical matrix switch based on polarization is presented, by controlling polarization states of signal beams to obtain non-blocking cross-connect. The detailed implementation of the node switches and the switching network are given. A 4×4 optical matrix switch fabricated with this method is tested, and the experiment result demonstrates that it characterizes by low insertion loss, low cross-talk, medium switching speed (ms), stability and technology maturity, which is quite suitable for small-sized optical matrix switch.
