Abstract
We investigate the diffraction of a polarized light by nonlinear spiral phase plate (NSPP) in the near zone, taking into account the three-dimensional structure of the optical element. The simulation of the NSPP diffraction is based on the finite difference time domain (FDTD) method. The results of numerical simulation of the NSPP diffraction for both homogeneous (linear and circular) and inhomogeneous (radial and azimuthal) polarized light are presented.
