By employing the concept of photon flux,the evolution of the phase and photon flux in the eigenmode state in three-wave mixing,and the requirements for the initial phase and photon flux in this state,are studied in the paper.A special state in which there are only exchanges of the photon flux but no phase variations in the three-wave mixing process is investigated.An all-optical switch based on the eigenmode pushpull nonlinear-optical-mirror is presented,and the properties of this all-optical switch are numerically calculated.The numerical results show that the performance stability is extremely good,and the intensity and phase of the output signal beams can be easily realized and controlled.
