We study degenerate spontaneous parametric downconversion in a structure composed of two linearly uncoupled resonators, which the linear properties fundamental and second-harmonic field can be engineered independently. As an example, we show that this system it is simple to generate photon pairs are nearly uncorrelated energy. These results extend use resonators case second-order nonlinear interactions.
