Abstract We propose a scheme to enhance nonlinear coupling between a two-mode optical cavity via parametric squeezing. Employing a two-mode squeezed vacuum state, we derive an effective Hamiltonian that reveals enhancement of nonlinear coupling. Numerical simulations demonstrate that the enhanced squeezing will cause the oscillation between the two-mode photon numbers of the system. The dissipation of the system is also considered, that the dissipation has a positive effect on the preparation of steady state via parametric squeezing. The result in our investigation could provide an effective simulation platform for the realization of quantum information process.
