Conditional preparation of a non-classical state in the continuous variable regime: theoretical study
Julien Laurat, Thomas Coudreau, Nicolas Treps +2
We study the characteristics of the quantum state of light produced by a conditional preparation protocol totally performed in the continuous variable regime. It relies on conditio…
Non-linear and quantum optics of a type II OPO containing a birefringent element Part 2 : bright entangled beams generation
Laurent Longchambon, Julien Laurat, Thomas Coudreau +1
We describe theoretically the quantum properties of atype-II Optical Parametric Oscillator containing a birefringent plate which induces a linear coupling between the orthogonally…
All-optical reshaping of light pulses using media
Kuanshou Zhang, Laurent Longchambon, Thomas Coudreau +1
We have developed a new method based on two cavities containing media to reshape optical pulses by an all-optical technique. The system is entirely passive \emph{i.e.}, a…
Non-linear and quantum optics of a type II OPO containing a birefringent element Part 1: Classical operation
Laurent Longchambon, Julien Laurat, Thomas Coudreau +1
We describe theoretically the main characteristics of the steady state regime of a type II Optical Parametric Oscillator (OPO) containing a birefringent plate. In such a device the…
Conditional preparation of a quantum state in the continuous variable regime: generation of a sub-Poissonian state from twin beams
Julien Laurat, Thomas Coudreau, Nicolas Treps +2
We report the first experimental demonstration of conditional preparation of a non classical state of light in the continuous variable regime. Starting from a non degenerate OPO wh…
