1. A method to manufacture a holographic optical element (HOE), the method comprising:
- impinging a plurality of wavefronts on a material having a first shape, the plurality of wavefronts to cause a first nano structure change in the material, the first nano structure change based on a second nano structure change, wherein the combination of the first nano structure change and the second nano structure change combine to form a structural attribute of a holographic optical element (HOE);
shaping the material to a second complex shape to cause the second nano structure change in the material; and
forming the HOE, the HOE comprising the material having the second complex shape and the structural attribute.

Abstract
Disclosed herein are devices and methods to provide a holographic optical element (HOE) having a modified shape and a structural attribute. At least one wavefront may be used to cause a first structure change in a material, used for the HOE, in a first shape. The material used for the HOE may be changed from the first shape to the modified shape to cause a second structure change in the material. The structural attribute in the material may be provided from a combination of the first structure change and the second structure change.
