1. A solid state optical beam steering device comprising:
a solid state body of electro-optical material wherein the solid state body of electro-optical material comprises a 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 conductor on the first face of the solid state body of the electro optic material;
a first resistive sheet on the second face of the solid state body of the electro optic material, wherein the first resistive sheet has a first side and a second side; and
wherein the conductor is electrically connected to the second side of the first resistive sheet; and
wherein the electro-optical material comprises NdNiO3, SmNiO3, PrNiO3, EuNiO3, or 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.
