Features of a Gaussian beam near-field diffraction upon variations in the relief height of subwavelength silicon optical elements
Features of the near-field diffraction of Gaussian beams and Laguerre-Gauss modes by silicon subwavelength optical elements with varying relief height were studied in this paper using a finite-difference time-domain method. Diffractive axicons and subwavelength ring gratings were considered as the o...
