Weak measurements of light chirality with a plasmonic slit

Gorodetski, Yuri; Bliokh, Konstantin; Stein, B; Genet, C; Shitrit, N; Kleiner, Vladimir; Hasman, Erez; Ebbesen, T W


We examine, both experimentally and theoretically, an interaction of tightly focused polarized light with a slit on a metal surface supporting plasmon-polariton modes. Remarkably, this simple system can be highly sensitive to the polarization of the incident light and offers a perfect quantum weak measurement tool with a built-in postselection in the plasmon-polariton mode. We observe the plasmonic spin Hall effect in both coordinate and momentum spaces which is interpreted as weak measurements...[Show more]
