For optical fibers as well as other waveguides, the excellence in between uniaxial and biaxial won't use, Considering that the propagation way is basically based on the waveguide.

In the same way, the polarization condition of the laser beam inside a laser crystal with thermally induced birefringence is distorted. The sort of distortion depends upon the placement, For the reason that birefringent axis features a varying (e.

Intrinsic birefringence will be the time period used to describe In a natural way developing materials that have asymmetry in refractive index that is course-dependent. These components incorporate quite a few anisotropic pure and artificial crystals, minerals, and chemical substances.

The optical route distinction is often a classical optical idea relevant to birefringence, and the two are described from the relative stage change concerning the regular and remarkable rays because they arise from an anisotropic material. Usually, the optical route difference is computed by multiplying the specimen thickness through the refractive index, but only once the medium is homogeneous and won't consist of major refractive index deviations or gradients.

polarization. Round birefringence can be induced by a magnetic field; This really is called the Faraday influence. Begin to see the post on optical action for aspects.

一些激光器晶体（例如，钒酸盐晶体和钨酸盐晶体）本身就具有双折射。这在需要无去极化损耗的线偏振输出时非常有用。 

is sometimes also used to be a amount (see beneath), usually described because the difference between remarkable and normal refractive index at a specific optical wavelength.

For incredible waves, exactly where the refractive index is determined by the angular orientation, You will find there's spatial wander-off: the way of energy propagation is a little bit tilted towards that from the vector.

光纤和其它波导中，采用有效折射率差值描述更好。这与传播常数虚部的差值直接相关。 

In some instances, mechanical worry has that impact. That can certainly be noticed having a piece of acrylic concerning two crossed polarizers: when tension is placed on the acrylic, a person observes colored designs ensuing from the wavelength-dependent influence of strain-induced birefringence.

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 direction is perpendicular to that and more info to the vector. The latter features a refractive index which is generally not

Anisotropic crystals, which include quartz, calcite, and tourmaline, have crystallographically distinct axes and interact with gentle by a system which is dependent upon the orientation with the crystalline lattice with regard to the incident gentle angle. When light enters the optical axis of anisotropic crystals, it behaves in the manner just like the interaction with isotropic crystals, and passes via at just one velocity.

For propagation alongside the optical axis, the electrical discipline can only be perpendicular to that axis, so that just one obtains the regular index for virtually any polarization route. In that problem, no birefringence is seasoned.

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：
