The polarization properties of cascaded substrate-mode holographic optical elements are analyzed and demonstrated. The design criteria for polarization selective and nonselective elements are given and verified with experimental volume holograms formed in dichromated gelatin emulsions. Using the experimental grating parameters, it is estimated that a reconfigurable optical bus with eight nodes can be made. Improved control of hologram construction parameters can increase this to more than 500 nodes. Use of this device with a reconfigurable interchange coupler and a multistage optical bus is also examined.
分析并演示了级联衬底模式全息光学元件的偏振特性。给出了偏振选择性和非选择性元件的设计标准，并用在重铬酸盐明胶乳剂中形成的实验体全息图进行了验证。利用实验光栅参数，估计可以制造出一个具有八个节点的可重构光总线。改进全息图构建参数的控制可将其增加到500多个节点。还研究了将该器件与可重构交换耦合器和多级光总线一起使用的情况。
