Paper Abstract

Polarization devices developed for fiber optic systems are pigtailed. These pigtails, built with standard single-mode optical fiber (~1 m long) modify the input and output characteristics of the signal's polarization state. Even though this contribution is negligible when the fibers are kept straight, it increases when they are wound up to form compact systems. In this work, we used Mueller calculus and experimental results to analyze the polarization performance of helically wound single-mode fibers. These results have been used to propose the cascaded helical structures we have built. Using linear and circular input polarization states and the Poincaré sphere it is shown that to control the total birefringence the relative orientation of the symmetry axes of these helices must be varied. The experimental results obtained for the birefringence of these structures demonstrates that it is possible to minimize their birefringence contribution within a limited spectral bandwidth.
