Abstract
An optical data apparatus has a first polarization splitter configured to receive an input and split the input into first and second orthogonal polarizations. A second polarization splitter is included and configured to combine the first and second orthogonal polarizations. A non-reciprocal phase rotator is positioned between the first and second polarization splitters. At least one birefringent crystal is positioned between the first and second polarization splitters to create wavelength dependent bi-directionality.
