Chimento, P.F. (author), Alkemade, P.F.A. (author), 'T Hooft, G.W. (author), Eliel, E.R. (author)We respond to a Comment on our Letter [Opt. Lett. 37, 4946 (2012)], in which we reported on the spin-to-orbital optical angular momentum conversion of a circular nanoslit in a thin metal layer. We claimed, in an unfortunately worded sentence, that the conversion efficiency was independent of the slit’s dichroism, which the Comment pointed out...journal article 2013

Chimento, P.F. (author), Alkemade, P.F.A. (author), 'T Hooft, G.W. (author), Eliel, E.R. (author)We demonstrate partial conversion of circularly polarized light into orbital angular momentum-carrying vortex light with opposite-handed circular polarization. This conversion is accomplished in a novel manner using the birefringent properties of a circular subwavelength slit in a thin metal film. Our technique can be applied over a very wide...journal article 2012

Chimento, P.F. (author), Kuzmin, N.V. (author), Bosman, J. (author), Alkemade, P.F.A. (author), 'T Hooft, G.W. (author), Eliel, E.R. (author)We have experimentally studied the polarization-dependent transmission properties of a nanoslit in a gold film as a function of its width. The slit exhibits strong birefringence and dichroism. We find, surprisingly, that the transmission of the polarization parallel to the slit only disappears when the slit is much narrower than half a...journal article 2011
