Abstract
We show that a nonlinear asymmetric directional coupler composed of a linea r waveguide and a nonlinear waveguide operating by nondegenerate parametric amplification is an effective source of single-mode squeezed light. This i s demonstrated, under certain conditions and for specific modes, for incide nt coherent beams in terms of the quasiprobability functions, photon-number distribution and phase distribution.
