Optical metasurfaces can manipulate a light wavefront without traditional lenses. They can include pillars with subwavelength dimensions on a substrate. The pillars can vary in size, shape, and spacing across a surface of the substrate. Each pillar size and shape can diffract incident light and provide a unique electromagnetic response. The metasurface can provide desired light wavefront manipulation without the thickness of traditional lenses. The metasurface can overcome the aberration problem of traditional lenses. An overcoat layer can be located at a distal-end of the pillars. Pillar pitch can be adjusted for uniform spacing between pillars, and uniform overcoat coverage. The overcoat layer can protect the pillars. An alternative to the overcoat layer is a solid fill-material filling gaps between the pillars.

A reflective wire grid polarizer (WGP) can include an array of wireson a face of a substrate, with channelsbetween adjacent wires. The wirescan have certain characteristics for WGP performance, such as index of refraction, alternating high/low index continuous thin films, thickness of layer(s), duty cycle, reflective rib shape, a curved side of transparent ribsor, aspect ratio, or combinations thereof.

A device includes an optic in an at least partially rigid scaffold. The scaffold is permeated, at least temporarily during a writing process, by writable media. The optic may be written into a writable volume in the scaffold defined by the writable media. The optic may be written by exposing the writable media to incident light to cause a material property change in the writable media within the writable volume.
