Abstract:
1. An apparatus comprising a plurality of electrodes including a first electrode, a second electrode complementary to the first electrode, and a third electrode complimentary to the second electrode, each of the plurality of electrodes aligned relatively parallel to each other; and a multi-segment optical waveguide including optically active material and comprising a first segment positioned between the first and second electrodes, and a second segment positioned between the second and third electrodes, the second segment to receive light from the first segment and to propagate the light received from the first segment between the second and third electrodes; the refractive index of the optically active material of the first segment to change based on an electrical difference applied to the first and second electrodes, and the refractive index of the optically active material of the second segment to change based on an electrical difference applied to the second and third electrodes; wherein the plurality of electrodes further comprises a fourth electrode complementary to the third electrode, the multi-segment optical waveguide further comprising a third segment, to receive light from the second segment, positioned between the third and fourth electrodes, the refractive index of the optically active material of the third segment to change based on an electrical difference applied to the third and fourth electrodes.
