Flat-Top Focal Spot and Polarization Conversion Obtained in Tightly Focused Circularly Polarized Light
In this paper, using the Richards–Wolf equations, the focusing of circularly polarized light with flat diffractive lenses is considered. It is shown that, as the numerical aperture (NA) of the lens increases, the size of the focal spot first decreases and then begins to grow. The minimum focal spot...
