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. WebAn optic axis is a direction rather than a single line: all rays that are parallel to that direction exhibit the same lack of birefringence. [1] Crystals may have a single optic axis, in which case they are uniaxial, or two different optic axes, in which case they are biaxial. Non-crystalline materials generally have no birefringence and thus ...
