Interaction of highly focused vector beams with a metal knife-edge
P. Marchenko, S. Orlov, C. Huber +4
We investigate the interaction of highly focused linearly polarized optical beams with a metal knife-edge both theoretically and experimentally. A high numerical aperture objective…
On the experimental investigation of the electric and magnetic response of a single nano-structure
P. Banzer, U. Peschel, S. Quabis +1
We demonstrate an experimental method to separately test the optical response of a single sub-wavelength nano-structure to tailored electric and magnetic field distributions in the…
Extraordinary transmission through a single coaxial aperture in a thin metal film
P. Banzer, J. Kindler, S. Quabis +2
We investigate experimentally the transmission properties of single sub-wavelength coaxial apertures in thin metal films (t = 110 nm). Enhanced transmission through a single sub-wa…
Waveguide properties of single subwavelength holes demonstrated with radially and azimuthally polarized light
Jochen Müller, P. Banzer, S. Quabis +2
We investigate the transmission of focused beams through single subwavelength holes in a silver film. We use radially and azimuthally polarized light, respectively, to excite highe…
Focusing a radially polarized light beam to a significantly smaller spot size
R. Dorn, S. Quabis, G. Leuchs
We experimentally demonstrate for the first time that a radially polarized field can be focussed to a spot size significantly smaller (0.16(1) lambda^2) than for linear polarizatio…
The focus of light - linear polarization breaks the rotational symmetry of the focal spot
Ralf Dorn, Susanne Quabis, Gerd Leuchs
We experimentally demonstrate for the first time that a linearly polarized beam is focussed to an asymmetric spot when using a high-numerical aperture focussing system. This asymme…
