Mirror-type optical switch array

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.
