Geometry and topology in 3D polarization
Résumé
This presentation will give an overview of the local description of polarization for nonparaxial light, for which all three Cartesian components of the electric field are significant. The polarization of light at each point is characterized by a three-component complex vector in the case of full polarization and by a 3×3 polarization matrix for partial polarization. Standard concepts in paraxial polarization such as the degree of polarization, the Stokes parameters, and the Poincaré sphere, have generalizations for nonparaxial light that are not unique and/or not trivial. Particular emphasis is placed on geometric interpretations and their similarities and differences with those for the paraxial regime, as well as topological
features. An application of this formalism in super-resolution microscopy is presented.
