本文提出了光纤中孤子脉冲的电致伸缩相互作用理论。孤子激发声波在横向于光纤轴的方向上传播。光辐射在这些波上的散射导致光脉冲到达时间的定时抖动。我们认为这种效应是光对声波的非线性自散射。由于声学寿命的值可以达到约100 ns的值，因此对于单个光脉冲以及对于作为整体的光脉冲序列，可以观察到声波上的自散射。得到了由声波激发引起的单孤子自频移值与孤子持续时间的关系。当孤子持续时间τ（sol）> 14 ps时，声波孤子的自频移大于拉曼孤子的自频移，所得理论结果很好地描述了光纤中孤子脉冲串的长程相互作用。得到了在高比特率、超长孤子通信系统中，由于光脉冲间的电致伸缩相互作用而引起的误码率的数值。
We present the theory of electrostrictional interaction of soliton pulses in optical fibers. Solitons excite acoustic waves propagating in the direction transverse to the fiber axis. Scattering of optical radiation on these waves leads to a timing jitter of the optical pulses arrival time. We consider this effect as nonlinear self-scattering of light on acoustic waves. Because of the fact that a value of acoustic lifetime can reach a value of about 100 ns self-scattering on acoustic waves can be observed for a single optical pulse as well as for an optical pulse sequence as a whole. The value of single soliton self-frequency shift due to excitation of acoustic waves as a function of soliton duration have been obtained. For soliton duration tau(sol) > 14 ps an acoustic wave soliton self-frequency shift is larger than the Raman soliton self-frequency shift.The obtained theoretical results describe well the long-range interaction of soliton pulse trains in an optical fiber. The value of bit error rate due to electrostrictional interaction of optical pulses in high bit rate, ultra long soliton communication systems have been obtained.
