Abstract
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.
Claims20
A device comprising:
- a porous medium comprising a writable volume, the writable volume defined via a writable medium that at least temporarily permeated pores of the porous medium;
- and
- a voxel formed within the writable volume via optical absorption by the writable medium.
A method of manufacture including:
- generating a porous medium with a writable volume by porosifying at least a portion of a substrate;
- and
- in the writable volume within the porous medium that at least temporarily permeated pores of the porous medium, generating a voxel by:
- focusing incident light into the writable volume to cause a material property change within a writable medium through optical absorption;
- and
- while causing the material property change, fixing a position of the voxel within the porous mediums.
A method including:
- generating a porous medium including a writable volume by porosifying at least a portion of a substrate;
- focusing incident light into the porous medium including the writable volume, the writable volume defined via a writable medium that at least temporarily permeates pores of the porous medium;
- and
- writing, via optical absorption of the incident light, a voxel in the writable medium within the writable volume in the porous medium.
