Experimental optical study demonstrates strong polarization-preserving lateral transmission contrast in metal-coated nanogratings, indicating a reciprocal route for asymmetric light steering.
Directional metal coating breaks lateral mirror symmetry in a reciprocal dielectric nanograting. Opposite in-plane illumination directions redistribute optical power differently among diffraction and absorption channels, producing strong polarization-preserving lateral transmission contrast. More details can be found in the Research Article by Ye Ming Qing, Shunsuke Murai, Koichi Okamoto, and co-workers (DOI: 10.1002/nap2.70244).
