本文提出了一种自适应波形控制方法来优化非线性光纤光谱滤波方法中的光子数压缩。数值计算表明，在脉冲被送入光纤之前对频谱相位进行调制，可以使sech包络脉冲产生大于-8dB的压缩。当脉冲被最佳整形时，光子数涨落的量子互相关变为均匀的负值。
We propose an adaptive waveform-control approach to optimize photon-number squeezing by the nonlinear fiber spectral filtering method. More than -8-dB squeezing of the sech envelope pulse is numerically predicted when the spectral phase is modulated before the pulse is sent to a fiber. The quantum cross correlations of the photon-number fluctuation become uniformly negative when the pulse is optimally shaped.
