Complete vectorial optical mode converter using multi-layer metasurface.

ABSTRACT: Vectorial optical mode converters that can transform orthogonal sets of multiple input vector beams into other orthogonal sets are attractive for various applications in optics and photonics. While multi-plane light conversion (MPLC) and metasurface technologies have been explored to individually address multiple spatial mode conversion and polarization mode manipulation, there has been no universal methodology to simultaneously convert a set of multiple vectorial modes with spatially non-uniform wavefronts and polarizations. Here, we present a general device framework to achieve complete vectorial mode conversion based on the MPLC concept incorporating multi-layer metasurfaces. The effectiveness of our method is confirmed experimentally by demonstrating 6-mode (3 spatial modes × 2 polariz
