Abstract

In this work we review some techniques useful for the generation of vortex beams and vector beams. We start from geometric-phase components such as q-plates or polarization diffraction gratings. Then we show that these components can be implemented and/or combined with liquid-crystal spatial light modulators in order to achieve higher control of the polarization and diffraction properties of the modulated beam. We show some examples where spiral phases and different diffraction grating designs are combined encoded with different polarizations to generate multiple vortex and vector beams. Employed in an inverted configuration, the same components can be employed to detect vector beams. Such arrangements can be used to generate vector-beam based polarimetry.
