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.

Volumetric optical integrated circuits

Methods and apparatus for concentrating light into a specified focal volume and for collecting light from a specified volume. Incident light is coupled through a plurality of successive transmissive asymmetric microstructure elements. The succession of transmissive asymmetric microstructure elements may be designed by representing an electromagnetic field as a linear combination of eigenmodes of one of the succession of transmissive asymmetric microstructure elements. The asymmetric microstructure elements are represented as a plurality of mesh lattice units and eigenmode solutions to Maxwell's equations are obtained for each mesh lattice unit subject to consistent boundary conditions. S-matrix formalism is employed to calculate a field output and weighting coefficients for the eigenmodes are selected to achieve a specified set of field output characteristics.
