Numerical simulation plots of Eq. (18) for χ(2)–χ(3) interaction with different numbers of χ(3) waveguides; evolution of quadrature variances in the (a) χ(2) waveguide (SX,1), and (b) χ(3) waveguides (SX,1, SY,1). The other input parameters are fixed at ς = 2, α1 = α2 = α3 = 0, Ω = ω = 2, Jn = 2, kn = 0, g = 10–7 and χ = 0.01.
