Abstract
We extend the existing vector vortex beams and demonstrate the creation of the generalized vector vortex beams, which is based on the superposition of any pair of orthogonal polarized base vectors with different spiral phases. Besides, we propose and experimentally demonstrate a flexible optical configuration, which modulates the generalized vector vortex beams through the phase-only liquid crystal spatial light modulators. Compared with the conventional vectorial modulation techniques, the explicit superposition and coaxial alignment of two laser beams are not required in our scheme. The theoretical derivation based on Jones matrix is demonstrated, and we experimentally verify the distribution of polarization and phase by measuring Stokes parameters and interference fringe, respectively. Such a proposed light field has potential applications in the domains as optical communication, nanoparticle manipulations.
