Vector beams have shown great promise for applications ranging from near-field optics to nonlinear optics. Here, we experimentally demonstrate a highly efficient and broadband metasurface-based polarization converter that can realize linear polarization rotation with more than 0.9 conversion efficiency over a 1300 nm bandwidth in the short-wave infrared band. Building upon this broadband polarization converter, we design a meta-reflectarray that is capable of generating arbitrary vector beams with the efficiency of >0.8 from 1200 nm to 2500 nm and therefore enable a wide range of applications including optical imaging, optical communication, and data encryption.
