Longitudinal component of the Poynting vector of a tightly focused optical vortex with circular polarization

Longitudinal component of the Poynting vector of a tightly focused optical vortex with circular polarization

We numerically investigated the focusing of optical vortices with the wavelength λ = 532 nm and right-hand circular polarization by using a diffractive lens with the numerical aperture NA = 0.95. The simulation was carried out using the Richards-Wolf formulae and the FDTD-method. The focusing of opt...
