Abstract
An example system includes a bulk steering crystal apparatus having a first lens face and a second concave face. The example bulk steering crystal apparatus further includes a number of steering portions interposed between the first lens face and the second concave face, where each of the steering portions includes a bulk substrate portion including an electro-optical material and a corresponding high-side electrode electrically coupled to the corresponding one of the number of steering portions.
Claims14
A system, comprising:
- a bulk beam steering crystal comprising an electro-optical material, wherein the bulk beam steering crystal comprises a solid material;
- a first lens positioned in optical communication with the bulk beam steering crystal;
- a second lens positioned in optical communication with the first lens;
- wherein the second lens is optically interposed between the first lens and the bulk beam steering crystal;
- and
- a bulk beam steering circuit structured to adjust a voltage drop across the bulk beam steering crystal, and thereby steer an electro-magnetic (EM) beam incident on the bulk beam steering crystal, and wherein the voltage drop comprises a continuous voltage gradient.

An apparatus, comprising:
- a bulk substrate comprising an electro-optical material, wherein the bulk substrate comprises a solid material;
- a transparent low-side electrode positioned on a first side of the bulk substrate;
- a high-side electrode positioned in electrical proximity to a second side of the bulk substrate;
- and
- a varifocal lens (VFL) circuit structured to adjust a continuous voltage gradient across the bulk substrate, thereby operating the bulk substrate as a VFL.
