High efficiency (reflectionless) conversion from free propagating photons to bound surface plasmon polaritons is realized in the visible range. On page 957, F. Ye, M. J. Burns, and M. J. Naughton demonstrate theoretically and experimentally that asymmetric, periodic, two‐element metal‐insulator‐metal structures can serve as reflectionless directional convertors between freely propagating visible photons and surface plasmon polaritons. These results are meaningful for varied applications in integrated nanoplasmonics, plasmonic logic, and plasmonic light harvesting.
