Abstract
Certain exemplary embodiments can provide a system, machine, apparatus, device, manufacture, circuit, composition of matter, and/or user interface adapted for and/or resulting from, and/or a process, method, and/or machine-readable medium comprising machine-implementable instructions for, activities that can comprise and/or relate to, generating a gradient in an index of refraction of a material.
Claims21
1-26. (canceled)
An electro-optic device comprising:
- a first electrode structure comprising:
- a first electrode layer comprising a concentric first plurality of electrode rings, each adjacent pair of electrode rings from said first plurality of electrode rings separated by a corresponding first layer separator from a concentric plurality of first layer separators;
- and
- a second electrode layer comprising a concentric second plurality of electrode rings, each adjacent pair of electrode rings from said second plurality of electrode rings separated by a corresponding second layer separator from a concentric plurality of second layer separators;
- wherein:
- said first electrode layer is positioned parallel to said second layer;
- a rotational axis of the first electrode layer is co-incident with a rotational axis of the second electrode layer;
- and,
- when view from a point along the rotational axis, an electrode ring from the first layer is not optically aligned with a spatially nearest electrode ring of the second layer.
