Description of spun fibers within the Jones matrix formalism in modeling of fiber-optic devices

We obtained an expression for Jones matrix of a real spun fiber which take into account a slight deviation of the fiber properties from the idealized case with polarization eigenstates in the form of right and left circular polarizations. The performed experiments with the spun fiber revealed the parameter deviations of the polarization modes of the real spun fiber from the idealized model and allowed estimation of this deviation level. The features of using the Jones matrix of a real spun fiber in the analysis of practical fiber-optic circuits and modeling their signals were considered.
