Birefringence is formally defined as the double refraction of light in a transparent, molecularly ordered material, which is a manifestation of the existence of orientation-dependent differences in refractive index. Many transparent solids are optically isotropic, meaning that the index of refraction is equal in all ...
WebAn optic axis is a direction rather than a single line: all rays that are parallel to that direction exhibit the same lack of birefringence. [1] Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial. Non-crystalline materials generally have no birefringence and thus ... WebDec 30, 2013 · In terms of the strategies to mitigate the residual birefringence, in a pioneering study of the polarization effects in optical fiber it was identified that the application of a uniform twist ...

The rays vibrate at … WebA study of photoinduced birefringence in bow-tie (stress-induced) high-birefringence (Hi-Bi) and low-birefringence (Lo-Bi) germanosilicate optical fibers is conducted by using 532-nm light. The study reveals that Hi-Bi fibers are insensitive to light polarized along the fast axis, in contrast to Lo-Bi fibers, which are photosensitive along both axes.
WebReduction in residual birefringence of an optical sample can also be performed after the component has been fabricated. Annealing performed on aspheric glass lenses has been shown to reduce stress and therefore birefringence by up to a factor of five2. Using a Mueller matrix polarimeter, J. Wolfe and R. Chipman studied the affect of annealing ...
Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive … See more A mathematical description of wave propagation in a birefringent medium is presented below.
