Prediction of strong quantum correlations between the orthogonally polarised spatial solitons produced in a vectorial Kerr medium

UFC has a long experience in the study, both at the experimental and theoretical level, of soliton arrays produced by a mechanism of modulational instability in a in planar waveguide having a Kerr nonlinearity. They have shown at the beginning of the project that quantum noise plays a central role in the spatio-temporal dynamics of these solitons. In collaboration with ENS, they have then theoretically investigated the spatial distribution of quantum fluctuations and correlations in 2D Kerr solitons and soliton arrays.

A first important result has been obtained in the case of the vectorial Kerr single soliton, namely an almost perfect anti-correlation between the fluctuations of the two components of opposite circular polarisations. A significant global and local squeezing was also found, both for the single soliton and for the array of solitons, while correlations between adjacent solitons in the array are very weak in all the studied configurations.
