Two optical switches were integrated on a single LiNbO(3) substrate to construct an array. Two switches were connected by a thin film waveguide in such a way that one of the outputs of the first switch leads to the entrance of the second switch. As an array, one input of the first switch fans out to three outputs controlled by an electrical signal. When no electric field is applied to either of the two switches, the relative outputs of the three terminals were 1.92, 0.05, and 0.01. When a field of 6 V/microm was applied only to the first switch, the three terminals responded to 0.02, 1.80, and 0.05. The relative outputs of the terminals switched to 0.01, 0.01, and 1.80 when both switches were activated.
两个光开关集成在单个铌酸锂（LiNbO₃）衬底上以构建一个阵列。两个开关通过薄膜波导连接，使得第一个开关的一个输出通向第二个开关的入口。作为一个阵列，第一个开关的一个输入扩展为三个由电信号控制的输出。当两个开关都不施加电场时，三个终端的相对输出分别为1.92、0.05和0.01。当仅对第一个开关施加6 V/μm的电场时，三个终端的响应分别为0.02、1.80和0.05。当两个开关都被激活时，终端的相对输出切换为0.01、0.01和1.80。
