“…This property becomes important as the NA is increased, and has been studied for several years now. Its most common intended applications reside in the areas of optical storage [10,11], microscopy and scanning optical microscopy [12][13][14], photonic force microscopy [15], lithography [16], laser micro-fabrication, particle guiding or trapping [17,18], and single molecule imaging [10,[19][20][21].…”

We present a system built to perform measurements of scattering-angle-resolved polarization state distributions across the exit pupil of a high numerical aperture collector lens. These distributions contain information about the three-dimensional electromagnetic field that results from the interaction of a tightly focused field and a sub-resolution scatterer. Experimental evidence proving that the system allows for high polarization-dependent sensitivity to sub-resolution displacements of a sub-resolution scatterer is provided together with the corresponding numerical results.

“…phase coding scheme can be extended to implement a multi-pixel array detector. Delaubert et al [28] has performed a quantum study of multi-pixel array detection and shown that it is possible to perform multipixel transverse spatial phase encoding. Possible implementation of a multi-pixel scheme would require the incorporation of multiple interferometers and the use of multi-squeezed beams or a multi-mode OPO system [29].…”

We propose a scheme which encodes information in both the longitudinal and spatial transverse phases of a continuous-wave optical beam. A split detector-based interferometric scheme is then introduced to optimally detect both encoded phase signals. In contrast to present-day optical storage devices, our phase coding scheme has an information storage capacity which scales with the power of the read-out optical beam. We analyse the maximum number of encoding possibilities at the shot noise limit. In addition, we show that using squeezed light, the shot noise limit can be overcome and the number of encoding possibilities increased. We discuss a possible application of our phase coding scheme for increasing the capacities of optical storage devices.

“…[9]). Increasing the number of correlated modes is of particular importance, for instance in the case of optical read-out technologies [12] and super-resolution techniques [13]. In this context, generating continuous-variable polarizationentangled light [1,2,3], which exhibits three or four mode correlations, is a first step towards increasing the phase space dimension.…”

A device to generate polarization-entangled light in the continuous-variable regime is introduced. It consists of an optical parametric oscillator with two type-II phase-matched nonlinear crystals orthogonally oriented, associated with birefringent elements for adjustable linear coupling. We give in this paper a theoretical study of its classical and quantum properties. It is shown that two optical beams with adjustable frequencies and well-defined polarization can be emitted. The Stokes parameters of the two beams are entangled. The principal advantage of this setup is the possibility to directly generate polarization-entangled light without the need of mixing four modes on beamsplitters as required in current experimental setups. This device opens up different directions for the study of light-matter interfaces and a generation of multimode nonclassical light and higher dimensional phase space.
