Abstract
When illuminated by a linearly polarized light, a high-aperture binary bi-axicon allows one to redistribute the axial contribution of different electric vector components, ensuring a maximal value of the longitudinal component and a minimal value of the transverse component on the optical axis. Such an asymmetric axicon for the wavelength 10.6 µm is fabricated on a silicon substrate using a lithography technique with plasma-chemical etching. Off-axis diffraction patterns were obtained experimentally through diaphragm-aided scanning of the focal plane.
