THE SMART TRICK OF BIREFRINGENT CRYSTAL THAT NOBODY IS DISCUSSING

Every time a beam is refracted for the floor of the birefringent crystal, the refraction angle will depend on the polarization route. An unpolarized light beam can then be break up into two linearly polarized beams when hitting surfaces of the material with non-ordinary incidence (double refraction).For optical fibers and various waveguides, it is
