Dispersive Full-Channel Jones Matrix Modulation in Elliptical Polarization Bases via a Single-Layered Metasurface. [PDF]
Adv Sci (Weinh)This work presents a dispersive full‐channel Jones matrix modulation strategy using single‐layer metasurface. By synergizing wavelength dispersion engineering with elliptical polarization bases, independent control of four Jones matrix channels is achieved across multiple wavelengths.
