Abstract
A birefringent device has a polarization separating device configured to separate a first composite light beam into first and second components thereof. The first and second components are orthogonally polarized with respect to one another. A first path is configured to transmit the first component and has a first optical path length. Similarly, a second path is configured to transmit the second component and has a second optical path length. The second optical path length is different from the first optical path length. A polarization combining device is configured to recombine the first and second components so as to form a second composite light beam. The second composite light beam is birefringent with respect to the first composite light beam.
