Abstract
A graded-index optical element may include a nanovoided material including a first surface and a second surface opposite the first surface. The nanovoided material may be transparent between the first surface and the second surface. Additionally, the nanovoided material may have a predefined change in effective refractive index in at least one axis due to a change in at least one of nanovoid size or nanovoid distribution along the at least one axis. Various other elements, devices, systems, materials, and methods are also disclosed.
Claims6
An optical array comprising:
- a plurality of graded-index optical elements each comprising a nanovoided material having a first surface and a second surface opposite the first surface, wherein:
- the nanovoided material is transparent between the first surface and the second surface;
- and
- the nanovoided material has a predefined change in effective refractive index in at least one axis due to a change in at least one of nanovoid size or nanovoid distribution along the at least one axis.
