Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
I claim: 1. A polarizer, comprising: a first inner axicon situated about an axis and configured to receive an input optical beam propagating along the axis, the first inner axicon including a polarizing reflective surface situated to reflect at least a portion of the input optical beam in a first state of polarization radially away from the axis; and a first outer axicon situated about the axis and having a reflective surface situated to at least partially reflect the portion of…
