ABSTRACT:
An article of manufacture, such as an electrically actuable light gate structure, includes a substrate which may comprise an electrooptically active solid-state light gate material. Spaced parallel electrodes are subdivided on that substrate into first and second electrode arrays alternating along an elongate region of the substrate. Individual terminals for the electrodes in each first electrode array are distributed along a line on one side of the elongate region, and individual terminals for the electrodes in each second electrode array are distributed along a line on the opposite side of the elongate region of the substrate. Any individual terminal of any one of the electrodes is spaced from the individual terminal of any other electrode by a center-to-center distance greater than the center-to-center spacing between that one electrode and the latter other electrode.
