Output Properties of Non-degenerate Parametric Amplifiers with Non-homogeneous Linear Losses
P. García-Fernandez, S. Balle, Francisco Javier Bermejo
The noise properties of non-degenerate parametric amplifiers with absorption losses which are different for the two beams are analysed by means of a semiclassical approach which enables the direct derivation of the Langevin equations for the optical fields from the quantum Heisenberg equations. Several statistical quantities are calculated and the implications of the present results for sub shot-noise absorption measurements are discussed finally.
