Azimuthal polarization and partial coherence

Journal of the Optical Society of America A, 2003
Partially coherent fields with the electric field parallel to the azimuthal coordinate are analyzed by use of the exact angular spectrum representation. The known results for fully coherent fields are used to find the permitted forms of azimuthally polarized, partially coherent fields.

Generating radial or azimuthal polarization by axial sampling of circularly polarized vortex beams

Applied Optics, 2007
A laser beam with circular polarization can be converted into either radial or azimuthal polarization by a microfabricated spiral phase plate and a radial (or azimuthal)-type linear analyzer. The resulting polarization is axially symmetric and is able to produce tightly focused light fields beyond the diffraction limit. We describe in detail the theory

Directly modulated azimuthally polarized vector beam laser design

Applied Optics, 2022
Directly modulated vector beam lasers are increasingly desirable for wide applications ranging from optical manipulation to optical communications. We report the first, to our knowledge, high-speed directly modulated vector beam laser with azimuthally polarized emission. It is a microcylinder cavity interacted with a proper second-order grating on top,

Radial and azimuthal polarizers

Journal of Optics A: Pure and Applied Optics, 2006
A method for dividing an incoming beam into radially and azimuthally polarized beams is proposed and studied theoretically. A thin birefringent plate—with its optical axis perpendicular to its polished surfaces—inserted behind a focusing lens generates two foci. One can be associated with the azimuthally and other with the radially polarized components
