摘要
基于“超光”模型，本文得到了行波超导波态的带序参量准粒子激发能谱，并选择ＣａＦ２为纤芯的理想单模光纤，对其超导波基态光强和临界光强随光一声耦合强度的变化关系进行了数值模拟，给出了行波超导波态出现的具体物理条件．分析表明以超导波光强作为行波超导波态的特征参量是合适的．
Based upon the superlight model, the excitation energy of a quasipar-tide with order parameter is obtained. We calculated critical light intensity oftraveling-wave superguiding ground-state of a single-mode optical fiber and simu-lated numerically its relation as a function of photon-phonon coupling strength; thephysical condition that the photonic supcrguiding state exists is gived and the lightintensity is considered to be a character parameter.
