【摘要】 提出了一种新型的无冲突４端口榕树型开关网络．采用液晶列阵及偏振棱镜、三角棱镜、波片等光学元件，在光学上实现了这种网络，得到了由４端进到４端出的２４种全排列方式．更多还原

【Abstract】 In this Paper, a new kind of the nonblock four-port Banyan switching networkis proposed. Using some classical optical elementS, such as polarized prism, triangularprism, wavelength plates, and liquid crystal array polarized switch, we have demostratedit in optical experiment. 24 kinds of switching functions for the four-port Banyannetwork have been obtained.更多还原
