1. An optical body, comprising:
- a first multilayered fiber comprising layers of at least a first and a second polymer material, layers of the first polymer material being disposed between layers of the second polymer material, at least one of the first and second polymer materials being birefringent; and
a third polymer material surrounding the first multilayered fiber, the third polymer layer having a refractive index less than the refractive index of either of the first and second polymer materials.

Abstract
A polarizing film is made of multilayer polarizing fibers embedded within a matrix. The fibers are formed with layers of at least a first and a second polymer material. Layers of the first polymer material are disposed between layers of the second polymer material. At least one of the first and second polymer materials is birefringent. In some embodiments the thickness of the layers of at least one of the materials varies across the fiber. The fibers are be embedded within a material having a lower refractive index than either the first or second polymer material.
