(Received 00 Month 200x; In final form 00 Month 200x) We study experimentally parametric amplification in the continuous regime using a transverse-degenerate type-II Optical Parametric Oscillator operated below threshold. We demonstrate that this device is able to amplify either in the phase insensitive or phase sensitive way first a single mode beam, then a multimode image. Furthermore the tot...

Parametric amplifiers are known to squeeze the vacuum state of electromagnetic field, which results in predictable statistics photocounts at their output. However, recent theoretical work arXiv:1112.4159 predicts a very different statistical distribution for an amplifier based on Josephson junction. We test hypothesis experimentally and recover expected squeezed statistics. explain this discrep...
