各向异性透明晶体如方解石、石英等的折射率，是其固有的特性，称为永久双折射。

All nonlinear crystals for nonlinear frequency conversion are birefringent. It is because they're able to have their nonlinearity only by getting non-isotropic, Which also will cause birefringence.

直光纤只有很小的随机双折射，即使这样其中的光传输一段距离后偏振状态也会发生变化。存在保偏光纤，是利用了很强的双折射来抑制这些效应。 

the remarkable index , but a instead a mix of and . This can be calculated with the next equation:

For optical fibers as well as other waveguides, the excellence concerning uniaxial and biaxial doesn't apply, For the reason that propagation direction is basically based on the waveguide.

Below you may submit concerns and remarks. So far as they get recognized via the author, they can appear higher than this paragraph together with the writer’s remedy. The creator will decide on acceptance depending on certain standards. Effectively, the issue should be of adequately wide curiosity.

文献中，双折射通常包含两种不同的含义。经典光学中，就是下面所说的双折射（double refraction）。

For optical fibers and also other waveguides, it is more appropriate to take into consideration the real difference of helpful refractive indices. This is often instantly linked to the main difference in imaginary values from the propagation constants.

Straight optical fibers are sometimes nominally symmetric, but However exhibit some little diploma of random birefringence due to tiny deviations from excellent symmetry �?as an example because of bending, other mechanical tension or compact microscopic irregularities.

Transparent crystalline supplies are usually classified into two classes defined by the volume of optical axes current during the molecular lattices. Uniaxial crystals have only one optical axis and comprise the most important family of frequent birefringent specimens, such as calcite, quartz, and purchased synthetic or biological buildings. The other big course is biaxial crystals, which happen to be birefringent elements that element two independent optical axes.

The other polarization path is perpendicular to that also to the vector. The latter incorporates a refractive index which is generally not

Anisotropic crystals, like quartz, calcite, and tourmaline, have crystallographically unique axes and connect with light by a mechanism that may be dependent upon the orientation with the crystalline lattice read more with regard towards the incident light-weight angle. When gentle enters the optical axis of anisotropic crystals, it behaves in the manner comparable to the interaction with isotropic crystals, and passes via at only one velocity.

EKSMA Optics has many types of birefringent crystal resources like several nonlinear crystals, many of our laser crystals and Raman crystals and polarizing optics crystals.

在激光器技术和非线性光学中，双折射现象通常发生在非各向同性晶体中：
