Abstract

The invention provides an optical device, including a light-transmissive substrate, and a pair of different, parallel gratings including a first grating and a second grating, located on the substrate at a constant distance from each other, each of the pair of parallel gratings including at least one sequence of a plurality of parallel lines, wherein the spacings between the lines gradually increase from one edge of the grating up to a maximum distance between the lines, and wherein the arrangement of lines in the second grating is in the same direction as that of the first grating. A system utilizing a plurality of such optical devices is also disclosed. A change in the refractive index of the substrate yields an angular deviation of the output wave. The refractive index of the substrate can be dynamically controlled by external means, e.g. by applying an electrical field.
