Abstract
Disclosed are axial, radial or spherical gradient index (GRIN) lenses fabricated by layering composite polymer films into an hierarchical structure.
Claims31
A gradient index lens comprised of a multilayered composite GRIN sheet;
- wherein said multilayered composite sheet is comprised of a plurality of at least two multilayered polymer composite films;
- wherein each of said multilayered polymer composite films is comprised of a plurality of at least two alternating layers (A) and (B) represented by formula (AB)x, where x=2n, and n is in the range of from 4 to 18;
- wherein layer (A) is comprised of component (a) and layer (B) is comprised of component (b);
- and
- wherein said components (a) and (b) exhibit a different refractive index.
