Abstract
Noise-sustained patterns have been predicted in several optical systems including cavities filled with Kerr media and Optical Parametric Oscillators [1, 2]. In OPO’s, due to birefringence, walk-off between pump and signal appears. This walk-off is responsible for the existence of a convective regime, in which a transverse pattern arises as a macroscopic manifestation of amplified and spatially structured quantum noise, with magnification factors of several orders of magnitudes. These noise-sustained structures are interesting candidates for the study of quantum correlations at a macroscopic level. However, standard methods to calculate quantum fluctuations are not helpful in this situation. Linearization schemes, usually invoked to use a positive-definite Wigner distribution, can not be applied since the reference state is unstable and fluctuations are amplified. P-positive representation is also not useful because of trajectories which diverge from the reference unstable state.
