Claim 15:
16. A beam steering device, comprising:
a substrate defining a cavity and having a first refractive index;
an electroactive material, disposed within the cavity and having a variable refractive index;
a first overlay, coupled to the substrate, to receive an incident light beam orthogonal to a first plane of the first overlay and to couple the incident light beam into the electroactive material;
a second overlay coupled to the substrate and defining a second plane tilted with respect to the first plane to define a tilt angle between the first plane and the second plane, to receive the incident light beam from the electroactive material and to output, after refraction at the second plane, the incident light beam as an output light beam;
a third overlay coupled to the substrate and defining a third plane orthogonal to the first plane; and
a fourth overlay coupled to the substrate and defining a fourth plane parallel to the third plane,
wherein the electroactive material is operable to have a second refractive index different from the first refractive index based on the strength of a first electric field applied to the electroactive material between the first overlay and the second overlay and based on a strength of a second electric field applied to the electroactive material between the third overlay and the fourth overlay.
