Birefringence Wedges

  Birefringence is responsible for the phenomenon of double refraction whereby a ray of light, when incident upon a birefringent material, is split by polarization into two rays taking slightly different paths.Birefringence wedges are widely used in fiber optics such as isolators and other applications.
