For an optical component with some birefringence, you can specify the retardance, which happens to be the main difference in phase shifts for the two polarization directions.

All nonlinear crystals for nonlinear frequency conversion are birefringent. It's because they can have their nonlinearity only by getting non-isotropic, Which also causes birefringence.

The birefringence of nonlinear crystal materials permits birefringent period matching of nonlinear interactions. Basically, Therefore birefringence compensates the wavelength dependence of your refractive index.

If waves with distinctive polarization Instructions propagate alongside one another inside the waveguide, their period relation is restored just after integer multiples on the propagation defeat size.

For optical fibers along with other waveguides, the excellence between uniaxial and biaxial doesn't apply, For the reason that propagation course is basically determined by the waveguide.

In laser technological know-how and nonlinear optics, the phenomenon of birefringence occurs mostly from the context of non-isotropic crystals:

即使是各向同性介质，也会由于存在不均匀的机械应力而产生双折射。这可以在两个交叉偏振器间放置一块有机玻璃观察：当施加应力到有机玻璃上，可以看到由于应力诱导的与波长相关的双折射效应而产生的彩色图像。

For optical fibers and various waveguides, it is a lot more acceptable to take into consideration the primary difference of productive refractive indices. This can be instantly connected with the real difference in imaginary values on the propagation constants.

Birefringence may be the property of some transparent optical elements the refractive index depends on the polarization course �?which can be described because the course of the electrical industry.

The birefringence of nonlinear crystal products permits birefringent period matching of nonlinear interactions. In essence, Which means birefringence compensates the wavelength dependence of the refractive index.

当线偏振激光光束在双折射晶体中传输时，如果偏振方向与双折射轴不重合，这时会包含两个方向具有不同波数的偏振部分。因此，在传输过程中，由于两偏振分量之间存在相对相位变化，于是偏振状态发生变化。

A lot of microscope makers take advantage of this sensitivity by giving a full-wave retardation plate or first-buy red compensator with their polarizing microscopes to aid scientists in pinpointing the Homes of birefringent materials.

Alternatively, the extraordinary wave deviates into the still left and travels with the electric vector perpendicular to that of your standard wave. Due to the fact calcite can be a negatively birefringent crystal, the normal wave is check here the gradual wave as well as the extraordinary wave is definitely the rapidly wave.
