Vectorial optical fields (VOFs) exhibiting arbitrarily designed wave-fronts and local polarization distributions are highly desired in photonics, yet complicated to generate by traditional methods. In this seminar, a series of work efficiently modulating arbitrary VOFs based on metasurfaces exhibiting full-matrix yet inhomogeneous Jones-matrix distributions will be introduced. The generic approach proposed in these works covers VOF generation in near- or/and far-field channels, with bi-/multi/ or even (in principle) infinite number of functionalities, which may inspire future researches as well as applications in optical manipulation and communications.
