| 摘 要： | 本文将Ｄａｍｍａｎｎ光栅［１，２］应用于光互连，提出了用Ｄａｍｍａｎｎ光栅实现完全混洗的方法．一个２×２的Ｄａｍｍａｎｎ光栅与一个成像透镜的组合，具有与四焦点透镜类似的成像作用．像面上，像的位置与Ｄａｍｍａｎｎ光栅的位置有关，适当选择光栅的位置可以实现不同元素数目及不同元素密度的完全混洗．本文给出了有关的理论推导及实验结果．

| Abstract: | In this paper, a new method to implement the Perfect shuffle3] with the Dammann grating1,2] used for optical interconnection is proposed. The combination of a 2×2 Dammann grating and an imaging lens is functional as a conventional lens composed of 4 off-axis subpherical lenses. The Position of the image point is determined by the distance between the Dammann grating and the output plane. Properly chosing the position of Dammann grating, we can realize Perfect shuffle with various density and various capacity. The theory and the experimental result was presented. |
