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…
A quantum study of multi-bit phase coding for optical storage
Magnus T. L. Hsu, Vincent Delaubert, Warwick P. Bowen +3
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 schem…
Optical storage of high density information beyond the diffraction limit : a quantum study
Vincent Delaubert, Nicolas Treps, Gao Bo +1
We propose an optical read-out scheme allowing a demonstration of principle of information extraction below the diffraction limit. This technique, which could lead to improvement i…
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…
Continuous-wave phase-sensitive parametric image amplification
S. Gigan, L. Lopez, V. Delaubert +3
We study experimentally parametric amplification in the continuous regime using a transverse-degenerate type-II Optical Parametric Oscillator operated below threshold. We demonstra…
