| We consider a system composed of two linearly mutually interacting, identical Kerr-like nonlinear oscillators. Assuming that the system initially is in a coherent state, we discuss the system's dynamics and concentrate on the field's mutual correlations. As a measure of such correlations, we apply the normalized first- and second-order coherence functions. We derive the analytical formulas for such functions showing that their time-evolution strongly depends on the linear coupling parameter. |
