Patent ID: 8033674

Claim:
An optical element comprising: a) a plurality of asymmetrically shaped domains dispersed in a matrix; b) wherein said asymmetrically shaped domains comprise a coating; and c) said matrix comprises a matrix material with a refractive index n mx , n my , and n mz , in the x, y, and z mutually orthogonal directions, respectively; and d) said coating comprises a coating material with a refractive index n cx , n cy , and n cz , in the x, y, and z directions, respectively; and e) said plurality of asymmetrically shaped domains comprise a domain material with a refractive index n dx , n dy , and n dz in the x, y, and z directions, respectively; f) wherein |n my −n dy |>0.01 or |n mx −n dx |>0.01.
