Quantum optics : Research activities

 

Parametric quantum optics

Parametric medium are among the most efficient to engineer the quantum fluctuations of light. Their utilisation inside a cavity lead the group to numerous experiments, which are split into two subsections :

Quantum Imaging : engineering the spatial quantum noise of light.

Parametric systems : parametric oscillators and quantum information.

Quantum noise in non linear cavities with cold atoms
Thanks to laser cooling, it is possible to obtain very slow atoms with high optical non-linearities.

Reducing the quantum noise with semi-conductors lasers
Semi-conductors lasers can emit light with squeezed intensity noise. We try to understand and improve this property.
