The angular momentum of light can be described by positions on a higher-order Poincaré
sphere, where superpositions of spin and orbital angular momentum states give rise to laser …

We report on the generation of mono-and polychromatic optical phase singularities from
micron-sized birefringent droplets. This is done experimentally by using liquid crystal …

Presents readers with the basic science, technology, and applications for every type of
adaptive lens An adaptive lens is a lens whose shape has been changed to a different focal …

Arbitrary vector beams (VBs) are realized by the designed polarization converters and
corresponding vector-photoaligned q-plates. The polarization converter is a specific twisted …

We investigate conversion of a linearly-polarized Gaussian beam to a radially-or an
azimuthally-polarized doughnut (0, 1)∗ Laguerre–Gaussian (LG) beams, performed with a …

A flexible approach is presented to generate vector beams with arbitrary polarization and
complex amplitude by means of two cascaded transmissive liquid crystal spatial light …

We show the opportunity of fabricating axially symmetric waveplates fine tuned to a desired
wavelength. High quality waveplates are obtained using liquid crystal polymer layers on …

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 …

In this paper, we propose a new approach for generating a vector beams array and
dynamically manipulating the polarization state of the beam array, based on a stable …

We propose and demonstrate a global and efficient approach for scalar and vectorial beam
shaping based on the interaction of circularly polarized light with a single piece of …
