Any time a beam is refracted within the area of a birefringent crystal, the refraction angle is dependent upon the polarization path. An unpolarized mild beam can then be split into two linearly polarized beams when hitting surfaces of the material with non-ordinary incidence (double refraction).

If the electric field has the course on the optical axis, a single obtains the amazing index ne. This can be done provided that the propagation path (extra precisely, the path of the k vector) is perpendicular for the optical axis. For another polarization direction, one particular then obtains the normal index no.

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。 

Birefringence is formally outlined as being the double refraction of sunshine within a clear, molecularly purchased material, that's manifested with the existence of orientation-dependent variances in refractive index. Several clear solids are optically isotropic, that means that the index of refraction is equivalent in all Instructions through the entire crystalline lattice.

Frequently yes. The refractive index as well as the index distinction between two polarizations is mostly wavelength-dependent. That is usually exploited for birefringent period matching, as an example.

Depending upon the symmetry with the crystal framework, a crystalline optical materials could be uniaxial or biaxial.

For an optical component with some birefringence, you can specify the retardance, which happens to be the real difference in stage shifts for The 2 polarization Instructions.

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 along with other waveguides, it is a lot more appropriate to take into consideration the real difference of efficient refractive indices. This can be right connected with the real difference in imaginary values of your propagation constants.

Although it is typical to interchangeably use the conditions double refraction and birefringence to point the power of an anisotropic crystal to individual incident light-weight into common and amazing rays, these phenomena essentially seek advice from distinct manifestations of the exact same course of action. The actual division of a lightweight ray into two visible species, Every single refracting at a different angle, is the entire process of double refraction.

而在非线性光学和激光器技术中，双折射则是一些非各向同性透明介质的折射率依赖于偏振方向（即电场方向）的性质。后者的性质时非偏振光束入射到该材料上时产生双折射。 

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

We offer a wide array of polarizers and polarization optics for many different employs. Picking out the proper polarization optic for your application generally is a bewildering activity, as we offer a wide range more info for many alternative utilizes.

Any time a beam is refracted on the area of a birefringent crystal, the refraction angle depends upon the polarization route. An unpolarized gentle beam can then be break up into two linearly polarized beams when hitting surfaces of the material with non-standard incidence (
