Claim 15:
16. A solid state optical beam steering device comprising:
an array of a plurality of optical beam steering elements;
wherein each optical beam steering element comprises:
a solid state body of electro-optical material wherein the solid state body of electro-optical material comprises any material of a class of hydrogen-doped phase-change metal oxide and wherein the solid state body has a first face and a second face opposite the first face;
a first transparent resistive sheet on a first face of the solid state body of electro-optical material, wherein the first transparent resistive sheet extends along the first face; and
a second transparent resistive sheet on a second face of the solid state body of electro-optical material, wherein the second transparent resistive sheet extends along the second face,

wherein an end of the first transparent resistive sheet and an end of the second transparent resistive are electrically connected to one another;
wherein the electro-optical material comprises NdNiO3, SmNiO3, PrNiO3, EuNiO3, GdNiO3 or any combination of NdNiO3, SmNiO3, PrNiO3, EuNiO3, GdNiO3, wherein a refractive index of the electro-optical material is configured to be controlled by a hydrogen doping density.
