Journal ArticleDOI
Generation of arbitrary vector beams with a spatial light modulator and a common path interferometric arrangement
TL;DR: A computer-generated hologram is introduced onto SLM for performing the beam conversion and optical realization of a variety of polarization configurations confirms the reliability and flexibility of the method.
Journal ArticleDOI
Optical orbital angular momentum from the curl of polarization
TL;DR: Optical trapping experiments validate that the vector fields, which have no additional phase vortex, exert torques to drive the orbital motion of the trapped isotropic microspheres.
Journal ArticleDOI
A new type of vector fields with hybrid states of polarization
TL;DR: An idea based on Poincaré sphere is presented and the creation of a new type of vector fields, which have hybrid states of polarization, which are anticipated to result in new effects, phenomena, and applications.
Journal ArticleDOI
Characterizing topological charge of optical vortices by using an annular aperture.
TL;DR: The spatial frequency property of the far-field diffraction intensity pattern of an optical vortex after passing through an annular aperture is explored and it is revealed that the spatial spectrum consists of alternate bright and dark rings and the number of the bright rings is nicely identical to the absolute value of the topological charge.
Journal ArticleDOI
Radial Hilbert transform with Laguerre-Gaussian spatial filters
TL;DR: Theoretical analysis and real experiments show that the LGSF possesses some advantages in comparison with the conventional spiral phase plate, which allows us to realize a radial Hilbert transform for achieving a high contrast edge enhancement with high resolution.
