Constructing Spin Density Vector Twists With Spin Density Singularity

Constructing Spin Density Vector Twists With Spin Density Singularity

In this article, we propose a non-orbital angular momentum (OAM) method for constructing the spiral twists of spin density (SD) vectors in three-dimensional (3D) optical fields. This is realized by generating strings of SD singularities in a longitudinal plane of a strongly focused HG10 mode beam wi...
