Abstract
Polarizers and polarizing beam splitter include one or more pairs of axicons that are configured to separate an input beam into a radially polarized component and a tangentially (or azimuthally) polarized component. A second axicon pair can be provided to recombine the tangentially polarized component so as to provide a more uniform beam intensity. The radially polarized component can be reflected or otherwise directed so that one or both the radial and tangential components are available for use.
