Abstract
When a light beam interacts with Kerr medium inside an optical cavity, its quantum fluctuations are squeezed.1 One can show that perfect squeezing can be obtained close to the turning points of the bistability curve. In order to implement such a scheme, one needs perfect Kerr media (with no losses, infinite frequency bandwidth and no excess noise) that are not available to date.2 We study here a new kind of Kerr medium, in which the nonlinearity has a mechanical origin: if a mirror is free to move, the radiation pressure will induce a coupling between its position and the intensity of the light beam, thus modifying the optical path in an intensity-dependent way.
