Spatial multimode entanglement within one laser beam
J. Janousek, K. Wagner, J-F. Morizur +4
Optical entanglement is a key requirement for many quantum communication protocols. Conventionally entanglement is formed between two distinct beams, with the quantum correlations…
TEM10 homodyne detection as an optimal small displacement and tilt measurements scheme
Vincent Delaubert, Nicolas Treps, Mikael Lassen +4
We report an experimental demonstration of optimal measurements of small displacement and tilt of a Gaussian beam - two conjugate variables - involving a homodyne detection with a…
Generation of Squeezing in Higher Order Hermite-Gaussian Modes with an Optical Parametric Amplifier
Mikael Lassen, Vincent Delaubert, Charles C. Harb +3
We demonstrate quantum correlations in the transverse plane of continuous wave light beams by producing -4.0 dB, -2.6 dB and -1.5 dB of squeezing in the TEM00, TEM10 and TEM20 Herm…
Quantum measurements of spatial conjugate variables: Displacement and tilt of a Gaussian beam
Vincent Delaubert, Nicolas Treps, Charles C. Harb +2
We consider the problem of measurement of optical transverse profile parameters and their conjugate variable. Using multi-mode analysis, we introduce the concept of detection noise…
Can optical squeezing be generated via polarization self-rotation in a thermal vapour cell?
M. T. L. Hsu, A. Dantan, J. Cviklinski +9
The traversal of an elliptically polarized optical field through a thermal vapour cell can give rise to a rotation of its polarization axis. This process, known as polarization sel…
