Poincaré sphere representation for classical inseparable states of the electromagnetic field — •Annemarie Holleczek1,2, Andrea Aiello1,2, Christian Gabriel1,2, Christoph Marquardt1,2, and Gerd Leuchs1,2 — 1Max Planck Institute for the Science of Light, Günter-Scharowsky-Str. 1/Bau 24, 91058 Erlangen, Germany — 2Institute for Optics, Information and Photonics, University of Erlangen-Nuremberg, Staudtstr. 7/B2, 91058 Erlangen, Germany
Cylindrically polarized modes (CPMs) of the electromagnetic field are very intriguing objects as they combine a complex polarization pattern with a complex spatial pattern. We investigate theoretical subtleties underlying their structure, in particular, a thorough theoretical description for spatio-polarization modes is developed. We show that two hybrid Poincaré spheres can be introduced to represent simultaneously the polarization and the spatial degrees of freedom of CPMs in accordance with conventional ways of displaying properties of optical beams, such as the Poincaré sphere for polarization. Possible mode-to-mode transformations accomplishable with the help of conventional polarization and spatial phase retarders are shown within this representation.
