In this work we recognize new strategies involving optical wave-breaking for controlling the output pulse spectrum in nonlinear fibers. To this end, first we obtain a constant of motion for nonlinear pulse propagation in waveguides derived from the generalized nonlinear Schrödinger equation. In a second phase, using the above conservation law we theoretically analyze how to transfer in a simple manner the group-velocity-dispersion curve of the waveguide to the output spectral profile of pulsed light. Finally, the computation of several output spectra corroborates our proposition.
在这项工作中，我们认识到了涉及光波破碎的新策略，用于控制非线性光纤中的输出脉冲光谱。为此，首先我们从广义非线性薛定谔方程导出了波导中非线性脉冲传播的一个运动常数。在第二阶段，利用上述守恒定律，我们从理论上分析了如何以一种简单的方式将波导的群速度色散曲线转换为脉冲光的输出光谱轮廓。最后，几个输出光谱的计算证实了我们的命题。
