Abstract
In recent years, the on-demand generation of structured polychromatic fields has introduced the possibility of creating more complicated polarization states. However, the study of the curves traced by the polychromatic electric field has been limited to the paraxial case, leading to Lissajous-like curves. In contrast, the new zoo of the 3-dimensional polarization curves remain almost unexplored. In this work, we propose the analysis of the 3-dimensional polarization curves generated by non-paraxial polychromatic beams. The non-paraxial regime is achieved through vector diffraction by an aplanatic lens.
