1. An optical film, comprising:

  • a polymer matrix layer; and

    at least a first multilayered fiber embedded within the matrix layer, the 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;

    wherein the first multilayered fiber has a non-circularly symmetric cross-section having a longer dimension parallel to a first direction and a short dimension parallel to a second direction orthogonal to the first direction, the first direction being substantially parallel to the polymer matrix layer.
