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. Where the fibers
are non-circular in cross-section, the cross-section can be oriented
within the polarizer.
