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
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.)

Oops here is the link!! :)
