WebThe birefringence, as a parameter, is defined as the local absolute value of the difference between the propagation constants of both modes: where c is the speed of the light in vacuum and Δn is the refractive index difference, also called the degree of birefringence. In standard fibers, the degree of birefringence is about 10 -7. Webnor measured. To determine the parameters of the polariza-tion ellipse that can be observed, Eq. 2 must be trans-formed to the intensity observable domain.6 This transfor-mation can be done by taking a time average of Eq. 2 .
