Paper Abstract

In this paper, by using the finite-difference time-domain method we study the formation of optical vortices by amplitude spiral zone plates with the topological charge of 2 μm, the diameter of 8 μm and the focal length of 0.532 μm made in 0.1 μm metal film. Silver and gold are proposed as a material of relief. The Gaussian beams at the wavelength of 0.532 μm with left and right circularly polarization are considered as incident light. Analysis of amplitude, phase, and intensity for each electric field component shows the presence of phase singularities which produce vortex field with complex structure.
