    Hi,

    There's a new article about detecting light's orbital angular momentum,
    this time from Harvard, is this just a terminonly confusion with the
    light polarization or is it actually OAM? They use nano-etched gold
    holograms to act as a plasmonic resonator to distinguish light with OAM
    of -1,0,+1

    cheers,
    Jamie
     
  2. I guess a link to the article would help. Optical angular momentum
    seems to be a bit of a research 'fad' these days.
    At the last March APS meeting everyone was talking about topological
    insulators.
    (Not that that's has any relation to OAM... just another fad.)
