1. abstract : 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
   文摘:利用光子流概念研究了三波混頻中本征模狀態(tài)的相位和光子流的變化，以及該狀態(tài)對(duì)光波的初始相位和初始光子流的要求，研究了三波混頻中只有光子流的交換卻沒(méi)有相位變化的特殊狀態(tài)，提出了本征模狀態(tài)推拉式非線性光環(huán)鏡的全光開(kāi)關(guān)，并數(shù)值計(jì)算了這種全光開(kāi)關(guān)的性能，數(shù)值結(jié)果表明，該光開(kāi)關(guān)的性能穩(wěn)定性好，并且易于實(shí)現(xiàn)和控制輸出信號(hào)光的光強(qiáng)及相位
