Polarization control is essential for tailoring light-matter interactions and is the foundation for many applications such as polarization imaging, nonlinear optics, data storage, and information multiplexing. A linear polarizer, which is a polarization optical element that filters a specific linear polarization from unpolarized light, plays an important role in both polarization generation and manipulation. However, the generation of arbitrary polarization states other than linear polarization usually requires cascading of multiple optical polarization elements, including both linear polarizers and waveplates based on an
