We present a digital free-space photonic switch structure that uses exciton absorption reflection switch (EARS) arrays. The network topology of the switch is a banyan network. This switch structure uses microbeam interconnections to realize a compact switch fabric. The low-loss interconnection that is necessary for high-speed operation can be achieved by the use of an optical system based on birefringent plates. A prototype switch (based on an 8 × 8 EARS array) with fiber array pigtails is fabricated and used to demonstrate two-input, two-output switching of 8-Mbits/s signals. This digital switch may be applicable to large-scale, multistage switching networks for optical interconnections and broadband telecommunication switching systems.
我们展示了一种使用激子吸收反射开关（EARS）阵列的数字自由空间光子开关结构。该开关的网络拓扑结构是一种榕树网络。这种开关结构利用微光束互连来实现紧凑的交换矩阵。通过使用基于双折射板的光学系统，可以实现高速运行所需的低损耗互连。制作了一个带有光纤阵列尾纤的原型开关（基于8×8 EARS阵列），并用于演示8 Mbit/s信号的双输入、双输出切换。这种数字开关可能适用于用于光互连的大规模、多级交换网络和宽带电信交换系统。
