ABSTRACT:
An electro-optic device includes a niobium dioxide (NbO.sub.2) crystalline material, a light source for illuminating the crystalline material and means for applying an electrical field, which can be varied, to the crystalline material, so that the intensity of the light (or electromagnetic energy) passing through the crystalline material will be a function of the electrical field. A reactive ion-beam sputtering technique for fabricating NbO.sub.2 crystalline thin films suitable for use in these electro-optic devices is also disclosed.
