调制不稳定性可用于将连续光波转换为恒定背景上的脉冲串。这些脉冲是否可以转换成孤子是一个长期的讨论。我们通过使用更一般的数学背景，调用波动方程的 Akhmediev 呼吸器、Peregrine 孤子和 Kuznetsov-Ma 孤子解来澄清情况，并建议使用 Mach-Zehnder 干涉仪来消除背景。给出了由此获得的脉冲宽度和峰值功率的表达式，并确定了它们的孤子含量。事实证明，每个脉冲 95% 以上的能量都可以转换为孤子。
Modulation instability can be used to convert a continuous light wave into a train of pulses on a constant background. It is a longstanding discussion whether these pulses can be converted into solitons. We clarify the situation by using a more general mathematical context, invoking the Akhmediev breather, Peregrine soliton and Kuznetsov-Ma soliton solutions of the wave equation, and suggest the use of a Mach–Zehnder interferometer to remove the background. Expressions for the pulse widths and peak powers thus obtained are presented, and their soliton content is determined. It turns out that more than 95 % of each pulse’s energy can be converted to a soliton.
