Abstract
We study contradirectional couplers composed of two linearly coupled nonlin ear Kerr waveguides. Intensity-dependent equations of motion are approximat ely solved, using a short-length coupler as an analogue of reference device . It is demonstrated that the switching is accompanied by quantum effects, such as two-mode squeezing of vacuum fluctuations and photon antibunching i n single modes. (C) 2000 Elsevier Science B.V.
