Analysis of polarization mode dispersion of single mode elliptic-core optical fibers

Abstract

Analysis of polarization mode dispersion (PMD) of elliptical core single mode fibers used in optical communication networks are presented. The measurements are performed both by a frequency method, based on the Jones matrix eigenanalysis for different light wavelengths at the input of the component, and by an interferometric time domain method. The sensitivity of PMD to mechanical stress for different optical fibers and for different core ellipticities are determined. Finally, results and analysis concerning the PMD variation as function of circularity defaults of optical fiber cores are given.
