Paper Abstract

We analytically and numerically show that by introducing the asymmetry into the axicon design it becomes possible to generate the longitudinal electric field (E-field) component on the optical axis for linearly and circularly polarized incident beams. Binary axicons with high numerical aperture (NA) are fabricated in three configurations – axisymmetric and spiral ones, and bi-axicon – by electron beam lithography. Experimental measurements for the near-field diffraction of most common and easy to implement incident beams – linearly and circularly polarized – are conducted. The experimental results agree with the theoretical analysis.
