Arbitrary control of Jones matrix properties in a metasurface diffraction grating using matrix Fourier optics
Abstract
Metasurfaces are arrays of artificially engineered subwavelength nanostructures. Owing to the strong form birefringence of these nanostructures, metasurfaces provide a fascinating platform to realize novel polarization optics. Recently, we proposed a more general design strategy for polarization-dependent metasurfaces using Fourier optics principles applied to the Jones calculus. We use this to design metasurface devices with arbitrarily chosen polarization responses embedded on diffraction orders, such as polarizers, waveplates, and cases that are mixtures of the two. We fabricate these gratings (for operation at visible wavelengths) and test them with Mueller matrix polarimetry, showing agreement with design.
