Birefringence in optics
WebMar 31, 2000 · Optical birefringence describes the difference of a material's refractive index with direction. When birefringence is on the order of the change of the in-plane refractive index between adjacent material layers, surprising and useful optical effects occur. We refer to these effects as giant birefringent optics (GBO). WebIn fiber optics, polarization-maintaining optical fiber (PMF or PM fiber) is a single-mode optical fiber in which linearly polarized light, if properly launched into the fiber, ... However tiny amounts of random birefringence in such a fiber, or bending in the fiber, will cause a tiny amount of crosstalk from the vertical to the horizontal ...

Webbirefringence present in the practical fibers. However, a controlled and deliberate birefringence introduced in the fiber may be used to realize several in-line fiber optical components and devices. In this chapter, we will discuss this aspect, i.e., the applications of the controlled and deliberate birefringence introduced in the fiber.
