Abstract
A device is provided. The device includes a first liquid crystal (“LC”) cell configured to modulate an amplitude of a light beam. The device also includes a second LC cell stacked with the first LC cell and configured to modulate a phase of the light beam. The device includes a sandwiched electrode layer disposed between the first LC cell and the second LC cell. The sandwiched electrode layer includes a conductive polymer film configured to function as a common electrode layer for driving at least one of the first LC cell or the second LC cell.
