Abstract

AbstractPerfect vector vortex beams play a very important role in understanding complex structured beams due to their vortex nature and nonuniform polarization profiles. However, the generation of these beams suffers from a limited number of topological charges, bulky optical setup, lack of color information, and limited control along the light propagation direction. To tackle these fundamental and technical challenges, a metasurface approach to generating multiple grafted perfect vector vortex beams (GPVVBs) along the light propagation direction. GPVVBs with different colors are observed by changing the observation plane is proposed. Their polarization profiles are indirectly confirmed through the unique features in the modulated intensity profiles with an analyzer. Furthermore, the dynamic control of these beams is realized by continuously changing the incident polarization. Simultaneous control of color and topological charges in GPVVBs along the longitudinal direction provides more degrees of freedom for carrying information and has the potential to impact quantum science, singular optics, and optical communications.
