Possible squeezed states generated in a three-waveguide nonlinear coupler\noperating with second harmonic generation is discussed. This study is carried\nout using two well-known techniques; the phase space method (based on positive\nP-representation) and the Heisenberg-based analytical perturbative method. The\neffect of the key design parameters is analyzed for both codirectional and\ncontra-directional propagation. The optimal degree of feasible squeezing is\nidentified. Also, the performance and capacities of both methods are critically\nevaluated. For low levels of key design parameters and in the early stages of\nevolution, a high level of agreement between the two methods is noticed. In the\nnew era of quantum-based technology, the proposed system opens a new avenue for\nutilising nonlinear couplers in nonclassical light generation.\n
