Claim 21:
22. An optical metasurface device, comprising:
an optical resonator layer with a two-dimensional array of metallic pillars arranged in rows and columns, and a tunable dielectric material that has a tunable refractive index positioned within gaps between adjacent metallic pillars in each row of metallic pillars;
an optically reflective layer positioned between a substrate layer and the optical resonator layer to reflect incident optical radiation;
driver routing layers with a row conductor for each row of metallic pillars and a column conductor for each column of metallic pillars;
a transistor layer with a plurality of transistor devices, wherein each transistor device is connected to and configured to be selectively driven by one of the row conductors and one of the column conductors, wherein a subset of the metallic pillars in the optical resonator layer are active metallic pillars, and wherein each active metallic pillar is connected to at least one of the transistor devices in the transistor layer; and
a capacitor layer with a plurality of storage capacitors, wherein each active metallic pillar in the optical resonator layer is connected to one of the storage capacitors in the capacitor layer and one of the transistor devices in the transistor layer,
wherein the driver routing layers, the transistor layer, and the capacitor layer are positioned between the substrate layer and the optically reflective layer.
