Theoretical comparison between polarization mode dispersion and birefringence vectors in single mode fibers

الملخص EN

The polarization mode dispersion, ŕ, and birefringence, β, vectors have the same meaning in a certain cases, but in general they are different.

In this paper, we introduce a new theoretical comparison between these two vectors through the propagation in optical fibers.

The parameters ; the angle between f and ŕ, and the value of β depend on the adopted form of the vector β.

In addition, the value of ŕ depend on the number of orders that is used to for account the vector x.

We introduce also a new formula of the dynamical polarization mode dispersion equation which contains the circular birefringence and the higher orders of the vector ŕ.
