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.
