A combination of linear and circular birefringence will have as basis polarizations two orthogonal elliptical polarizations; the term "elliptical birefringence" however is rarely used.
Alternatively, stress permanently induced in the fiber will produce stress birefringence ; this may be accomplished using rods of another material included within the cladding.
For instance, choosing right and left circular polarizations as basis functions simplifies the solution of problems involving circular birefringence (optical activity) or circular dichroism.
A typical DFA has several tens of meters, long enough to already show this randomness of the birefringence axes.
American Mineralogist 61:1001–1004 The maximum birefringence δ is 0.15 and the measured value of 2V is 7°, calculated 12° to 8°.
A probabilistic nature of light-particle motion was first considered by Newton in his treatment of birefringence and, more generally, of the splitting of light beams at interfaces into a transmitted beam and a reflected beam.
