[Polarisation du CMB comme information complémentaire aux anisotropies]
L'origine de la polarisation du CMB est passée en revue. On insiste plus particulièrement sur l'information qu'elle contient : la nature des fluctuations primordiales, le lien avec le paradigme de l'inflation. On discute aussi les aperçus apportés sur des époques plus récentes : la réionisation précoce et la distribution de matière pour des hauts décalages vers le rouge.
The origin of CMB polarization is reviewed. Special emphasis is placed on the cosmological information encoded in it: the nature of primordial fluctuations, the connection with the inflation paradigm. Insights into more recent epochs are also discussed: early reionization and high redshift matter distribution from CMB lensing.
