Two-Mode Squeezed and Entangled Light Production in Parametric Oscillations

We investigate the statistical and quadrature squeezings, as well entanglement properties, of a two-mode light generated by non-degenerate parametric oscillations coupled to squeezed vacuum reservoir, employing solutions quantum Langevin equations. It is found that shows squeezing for all values time. Moreover, it observed reservoir growing amplitude pump mode enhance degrees entanglement. have also shown amounts are significant in region, where mean photon number higher, correlation lower.
