Focal intensity landscapes of tightly focused spatially varying bright ellipse fields

Pal, Sushanta Kumar; Kumar Singh, Rakesh; Senthilkumaran P. (IOP Publishing Ltd, 2022-04)

Vector vortex beams play an important role in tailoring tightly focused fields by creating an additional longitudinal component at the focal plane. Until now, mainly focusing properties of fundamental, higher order vector ...
Focused polarization ellipse field singularities: interaction of spin-orbital angular momentum and the formation of optical Möbius strips

Pal, Sushanta Kumar; Somers, Lavi; Singh, Rakesh Kumar; Senthilkumaran, P.; Arie, Ady (Institute of Physics, 2023-04-06)

We study here the intensity distribution and formation of optical polarization Möbius strips by tightly focusing of C-point singularity beams. These beams are characterized by a central circular polarization point (C-point) ...
