1. A photonic crystal optical body, comprising:
- a polymer matrix; and
an arrangement of polymer scattering fibers disposed within the matrix, the scattering fibers being substantially parallel to a first axis, positions of scattering fibers in the arrangement across a cross-section of the polymer matrix being selected so as to form a two-dimensional photonic crystal structure for light incident on the polymer matrix in a direction substantially orthogonal to the first axis.

Abstract
An optical element is formed by co-extruding to have an arrangement of polymer scattering fibers within a polymer matrix. The scattering fibers lie substantially parallel to a first axis. The scattering fibers are arranged at positions across the cross-section of the polymer matrix to scatter light transversely incident on the optical element in a direction substantially orthogonal to the first axis. The positions of the scattering fibers across the cross-section of the optical element may be selected so as to form a two-dimensional photonic crystal structure for light transversely incident on the optical element.
