Taking advantage of the narrow spectral selectivity of stimulated Brillouin scattering and its dependence with the relative polarization alignment between the pump and the stimulus, polarization selective spectral measurements are performed on the signal under test. Obtaining the spectra for three pairs of orthogonal polarization states of the pump, the three Stokes parameters are retrieved for each spectral component. Differential group delay is then calculated from the spectral evolution of the polarization state. info:eu-repo/grantAgreement/ES/MICINN/TEC2010-17869 info:eu-repo/grantAgreement/ES/MICYT/TSI-020100-2011-423 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.176 2013 ENGINEERING, ELECTRICAL & ELECTRONIC 54 / 246 = 0.22 2013 Q1 T1 OPTICS 20 / 83 = 0.241 2013 Q1 T1 PHYSICS, APPLIED 41 / 135 = 0.304 2013 Q2 T1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Subias, Jesús M.
