    Near-Perfect Efficiency for SHEL with Anisotropic Metasurfaces

    Article obtained from Photonics RSS Feed.

    POSTECH and KAIST researchers developed a method for achieving near-unity efficiency of the spin Hall effect of light (SHEL). The collaborators used an artificially designed metasurface capable of transmitting most light of one polarization — near-unity transmission — and reflecting light from the other. The method and the effect it delivered would improve microscopic optical device performance and effectiveness, including beamsplitters and optical switches.

    SHEL refers to a transverse and spin-dependent shift of light to the plane of incidence where it is reflected or refracted at an optical interface; when amplified, it can shift light that is several to tens of times greater than its wavelength. Previous attempts at…
