用反向传播法数值研究了光纤-布拉格-光栅孤子的量子涨落。结果表明，该光栅的带隙效应起到了非线性滤波的作用，导致了孤子的幅度压缩。压缩比在一定的光栅长度后趋于饱和，当脉冲能量略高于基孤子能量时，出现最佳的苏伊津比。
Quantum fluctuations of optical fiber-Bragg-grating solitons are investigated numerically by the back-propagation method. It is found that the band-gap effects of the grating act as a nonlinear filter and cause the soliton to be amplitude squeezed. The squeezing ratio saturates after a certain grating length and the optimal saueezine ratio occurs when the pulse energy is slightly above the fundamental soliton energy.
