Experimental investigation of amplitude and phase quantum correlations in a type II OPO above threshold: from the non-degenerate to the degenerate operation
Julien Laurat, Thomas Coudreau, Laurent Longchambon +1
We describe a very stable type II optical parametric oscillator operated above threshold which provides 9.7 0.5 dB (89%) of quantum noise reduction on the intensity differenc…
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…
