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…
Polarization squeezing of intense pulses with a fiber Sagnac interferometer
J. Heersink, T. Gaber, S. Lorenz +3
We report on the generation of polarization squeezing of intense, short light pulses using an asymmetric fiber Sagnac interferometer. The Kerr nonlinearity of the fiber is exploite…
Experiment towards continuous-variable entanglement swapping: Highly correlated four-partite quantum state
Oliver Glöckl, Stefan Lorenz, Christoph Marquardt +7
We present a protocol for performing entanglement swapping with intense pulsed beams. In a first step, the generation of amplitude correlations between two systems that have never…
