WebJul 13, 2024 · Birefringence in uniaxial materials. In linear optics, when treating anisotropic uniaxial materials we get the frensel equation. this equation gives us two solution for n. My problem is that according to Snell's law, if I have two different n, I suppose to get to different transimission angles (with two different k). Webmodel, the birefringence correlation length and the beat length are and , respectively. The two models that we have introduced describe the random evolution of the intrinsic birefringence of a fiber without spin. When the spin is applied, the local birefringence vector un-dergoes a rotation. If we define a spin function , i.e., the
