A mathematical description of wave propagation in a birefringent medium is presented below. Following is a qualitative explanation of the phenomenon. The simplest type of birefringence is described as uniaxial, meaning that there is a single direction governing the optical anisotropy whereas all directions perpendicular to it (or at a given angle to it) are optically equivalent. Thus rotating the material around this axis does not change its optical b… WebJun 15, 2001 · It requires (i) the measurement of the power Pout prism-coupled into the radiation modes of the waveguide as a function of the corresponding effective indices neff for both TE and TM polarizations; (ii) the measurement of the effective refractive index of the only extraordinary guided mode.
