A Higher-order poincaré ellipsoid representation for non-cylindrical vector beams

Discover Applied Sciences
The Higher-Order Poincaré Sphere (HOPS) provides a powerful geometrical tool for representing vector beams as points on the surface of a unitary sphere. Since a particular position on the surface represents any spatial mode regardless of its shape, this ...

Creation and detection of Vector Bessel Beams

, 2016
Bessel beams are optical fields which falls into the category of non-diffracting beams. Vector Bessel beams are vector beams possessing cylindrical symmetry. Cylindrically symmetric beams tend to have a tight focal point during propagation.

Generation of arbitrary cylindrical vector beams using mode-converting metasurfaces

Cylindrical vector beams (CVBs) are radially polarized or azimuthally polarized beams in the radiative near field. They resist diffraction within the Fresnel zone and exhibit a tighter focusing spot compared to linearly polarized beams.

Design of cylindrical vector beams based on the rotating Glan polarizing prism

, 2013
Recently the cylindrically polarized beams have been gained highly attention in the fields of particle manipulation, material processing, nanoscale imaging, etc. So the methods to create the cylindrically polarized beams become more important.

Two-photon induced photoluminance of gold nanorods using cylindrical vector beams

, 2011
Photoluminance of gold nanorods has been studied via two-photon excitation using cylindrical vector beams (CVBs). Based on our experiment results, CVBs cannot only be used for fast determining the three-dimensional orientation of gold nanorods, but also ...
