Independent and simultaneous tailoring of amplitude, phase, and complete polarization of vector beams

We present an approach that enables complete control over the amplitude, phase and arbitrary polarization state on the Poincaré sphere of an optical beam in a 4-f system with a spatial light modulator (SLM). The beams can be constructed from a coaxial superposition of x- and y-linearly polarized light, each carrying structured amplitude profile and phase distributions by using an amplitude-modulated mask imposed on the SLM. The amplitude, phase and polarization distribution of vector beams with four free parameters can be tailored independently and simultaneously by the SLM.
