摘要
研究了一种(3,3,2)矩形CC榕树网。根据(3,3,2)CC矩形榕树网的构造原则,得到其网络拓扑结构。然后,提出了(3,3,2)矩形CC榕树网的路由法则,完成了该网络的路径选择。最后,设计并提出了实现(3,3,2)矩形CC榕树网功能的光学实验模块,各级节点开关单元由位相型空间光调制器和偏振分光棱镜组成,级间互连则由光纤实现。分析了(3,3,2)矩形CC榕树网光学实验模块的功能特点,对基本开关单元性能参数进行了实验检测。结果表明,该实验模块能够完成输入信号光的交换和排序等操作,可应用于光通信和光信息处理中。
A(3,3,2) rectangular CC-Banyan network was studied.According to the construction principle of the CC-Banyan network,the topological graph of(3,3,2) rectangular CC-Banyan network was obtained,and then the routing rule of(3,3,2) rectangular CC-Banyan network was presented.Finally,a optical experimental setup of(3,3,2) rectangular CC-Banyan network was designed.Each stage of node switches consisted of a phase spatial light modulator and a polarizing beam-splitter,and the connection of neighboring stage was performed by a fiber.The theoretical analysis and experimental result show that the experimental setup can realize these functions including optical signal sorting and permuting etc.,which also can be used in the fields of optical communication and optical information processing.
