Experimental demonstration of frequency-degenerate bright EPR beams with a self-phase-locked optical parametric oscillator
Gaelle Keller, Virginia D'Auria, Nicolas Treps +3
We report the first experimental observation of bright EPR beams produced by a type-II optical parametric oscillator operating above threshold at frequency degeneracy. The degenera…
Generation of two-color polarization-entangled optical beams with a self-phase-locked two-crystal Optical Parametric Oscillator
Julien Laurat, Gaëlle Keller, Claude Fabre +1
A new 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-matche…
Entanglement of two-mode Gaussian states: characterization and experimental production and manipulation
Julien Laurat, Gaëlle Keller, Jose-Augusto Oliveira-Huguenin +5
A powerful theoretical structure has emerged in recent years on the characterization and quantification of entanglement in continuous-variable systems. After reviewing this framewo…
Experimental Generation of Large Quadrature EPR Entanglement with a Self-Phase-Locked Type II OPO Below Threshold
Julien Laurat, Thomas Coudreau, Gaelle Keller +2
We study theoretically and experimentally the quantum properties of a type II frequency degenerate optical parametric oscillator below threshold with a quarter-wave plate inserted…
Compact Source of EPR Entanglement and Squeezing at Very Low Noise Frequencies
Julien Laurat, Thomas Coudreau, Gaelle Keller +2
We report on the experimental demonstration of strong quadrature EPR entanglement and squeezing at very low noise sideband frequencies produced by a single type-II, self-phase-lock…
